That sounds similar to Ninite which makes a package of the apps for you. But it does it all at once from the ones you select. I think that I or someone else posted that a few weeks back.

Excellent!
Here's a tool, while not FOSS, that can make the job of installing multiple applications much easier:
http://www.almeza.com/
Multiset allows you to create a "player" which with one click will reinstall all your applications. I confess I may have done it wrong but the set I built allows me to install 24 applications with half a dozen clicks and loads everything in about 15 minutes.
I'm using this in my Goodwill recycling project so I can create an consistent load of the one-up computers we get donated.
For the computers that come in as matched units we build one image, clone it with Clonezilla and the volunteers image the other computers with the Clonezilla live CD and external USB hard drives.
While I do a have a 500gb drive with the master images, the volunteers use old 40 gig drives in external cases to do their imaging.
While setting up a Clonezilla server is a bit of a challenge, using Clonzilla as a standalone project is a wonderful and free solution.

Depending how you want to broadcast image computers, I have used udpcast
to broadcast a hard drive of a computer out to several others during
closed hours.
One thing to check out for imaging is http://fogproject.org
The fog server allows computers to pxe boot from it. It can create an
inventory of your machines, you can group machines together and tie them
all to the same image file, you can copy an image file out one by one or
multicast. It has a client app that can run on the computer to check for
tasks you assign to a machine. The client app can also rename computers
after the imaging is done. It keeps track of computers by MAC addresses
and associates them with the computer names. It also has a feature to
deploy printers but I have not used it.
I have been using fog here and there and also clonezilla for imaging as
well.
I find imaging computers helps me a lot when deploying new ones. I can
unpack 1 machine set up it the way I want it that is the same for all
the computers, and create an image of it. I store the image to either a
network share or a portable USB hard drive using Clonezilla.
I then start setting up new machines one at a time. I unpack the new
machine, and put it in the place of the old machine I am replacing. I
then boot off the clonezilla CD and copy my image file onto the machine.
When its done, I go through all the computer specific settings, computer
name, install what ever is specific to that machine, join it to the
domain, etc. When I am done that machine is ready to go and on to the
next one I go.
This in my opinion saves me time from finding a place to unpack all the
new machines, connect them all up, and prep them for deployment, then
unhook them all and deploy them.
Below is the handout I made up for the presentation I did at the last
Techconnections. I hope it helps! I don't think there is a reason to run
newsid on them. read this for more info about it

Imaging Computers using free tools
Submitted by Ed Liddle on Tue, 02/24/2009 - 23:43
Imaging computers can save a lot of time when deploying and reinstalling
windows. There are many tools that can be used to image or clone
computers. I am going to focus on using simple freely available ones.
There are several open source tools that can be used to image computers.
Some rely on creating a bit for bit copy of the hard drive, compressing
the file and storing it. Others keep track of the partition table and
the amount of used space on the drive and just store the data in the
used space. Some use a network, some do not require a network. The one I
have been using lately is the clonezilla live cd. I use it with a
portable USB hard drive to store images to along with parted magic to
resize and create partitions. I have used G4U (ghost 4 unix), G4L (Ghost
for linux), udpcast, and couple of other free imaging tools.
Personal experiences:
I started out using G4U and a sftp server on the network. This worked
well since it did a bit for bit copy of the hard drive. I was able to
deploy the images on many different types of hard drives ranging in
manufacturers and size ( smaller to bigger). The downside is the time it
takes to create and deploy an image in this way. It would take a couple
of hours to create an image and about 30 minutes to an hour to deploy
it. Not bad if you don't have a lot of machines to do or a lot of
different images to keep track of. I had about 2 or 3 main images I
would use, one for circ machines, one for public machines, and one for
staff machines. For multiple machines I found udp cast to be very fast
for copying one machine's hard drive to many others. I have used this
mainly on our laptops we use for classes and the public computers when I
set new ones up.
More recently I have been using clonezilla with a usb hard drive for
creating images and deploying images in combination with storing a
machine specific image on a linux partition on each machine. At my
library I often find myself setting up one machine at a time. In order
to image many staff machines at one time I would have to set them all up
in a room, network them together with a separate switch, image them with
a basic image, then manually set the computer names, generate new SIDS,
and join them to the domain. After all that is done then I have to
unhook each one, label them as to where they will go, and swap them out
with existing computers. Once the new machines are deployed occasionally
I will have to reinstall or re-image one to get rid of some of the
goodness that many windows nasties will give a user. If I re-image one,
I would use my basic image and afterwards go through the computer
specific settings. This way is definitely faster than doing a fresh
install the tried and true manual way. After using Clonezilla to create
images and deploy them from a usb drive it proved to be much faster than
sending a bit for bit image to or from a sftp server on the network.
My Current Method:
Desktop hard drives have a lot of wasted space on them in the library I
work at. Computers are coming with 80 gig hard drives. A typical windows
installation takes up 15 to 20 gigs which leaves 50 or 60 gigs of unused
space. Staff users save all their files to a file server. How can some
of this unused space be used on desktop hard drives? I decided to use
some of this space to store computer specific images on a linux
partition.
* Step 1:
On the machine I use to create my master image I use a linux
live cd called parted magic. Parted magic is a light weight
linux distro that has some useful tools. Among the tools is one
called gparted. Gparted can be used to manipulate existing
partitions and create new ones. I start out by shrinking down
the partition windows is installed on to make room for a 20 gig
or so linux partition. I create the ext3 linux partition and
format it using gparted. After this is done I proceed in booting
windows up, installing software, and updates to it along with
any non computer specific settings that need to be tweaked. I
also copy newsid and any other utilities I will need when I
perform the computer specific settings later in a folder on the
C: drive.
* Step 2:
I then use Clonezilla and create an image of the entire hard
drive on my USB hard drive. This takes about 15 to 40 minutes
depending on hard drive size and used space.
* Step3:
I unpack a new computer and set it up at the location it is
going to be in. I plug in my USB hard drive and boot the
clonezilla cd up to copy the hard drive image onto the new
machine. This takes about 15 minutes or so.
* Step4:
I boot into windows run newsid and tell it to rename the PC.
When its done, I install additional software if needed. I then
join the PC to the domain and make sure everything is working
correctly.
* Step5:
I boot up the clonezilla cd and image just the windows partition
to the linux partition on the computer's internal hard drive.
This provides a secure way to store the image file. When windows
is booted up it can not read or write to the linux partition.
This ensures the image file will not get deleted or infected by
any virus that runs in windows.
Its been my experience that I will have to reinstall windows on a
computer one or more times before the hard drive in the machine will
fail. Having a computer specific image stored locally on the computer
will allow me to quickly reinstall everything and perform windows
updates afterwards in a very timely manor. I estimate the time to
re-image the computer to take about 15-20 minutes add to that the time
it takes to pull down and install the updates it will need. A
guestimation for this would be about a 1/2 hour or so. Total time to get
the computer back in operation would be about 45 minutes. I have no
images taking up space on a file server waiting to be used. Re-imaging
does not effect the local network at all since the images are on locally
connected devices. I can take my external hard drive to our branch
library and deploy the same images there. Worst case scenerio if my
portable USB hard drive dies, I have several computers I can create a
new image from and tweak it accordingly to reuse.
Clonezilla also has an optional server that can be setup to use with a
network. Clonezilla can make use of a windows file server, ftp server,
and nfs server to store images. It can also be used to create a restore
DVD/cd.
Another network based imaging solution is fog project
http://www.fogproject.org/ Fog is a Linux-based, free and open source
computer imaging solution for Windows XP and Vista that ties together a
few open-source tools with a php-based web interface. Fog doesn't use
any boot disks, or CDs; everything is done via TFTP and PXE. Also with
fog many drivers are built into the kernel, so you don't really need to
worry about drivers (unless there isn't a linux kernel module for it).
Fog also supports putting an image that came from a computer with a 80GB
partition onto a machine with a 40GB hard drive as long as the data is
less than 40GB.
Cost:
$0 - NewSID
http://technet.microsoft.com/en-us/sysinternals/bb897418.aspx
$0 - Clonezilla http://clonezilla.org
$0 - Parted Magic http://partedmagic.com
$120 - 500 gig USB hard drive
Priceless - Short period of time it takes to get a PC back in service.
I hope this helps.
