[OPLINTECH] Magnetic Paint & WiFi

[joe]

You know, I hadn't thought about this when the question was posed, but 
if you are someone who really hates having cell phones ringing in your 
library, and wanted to set a quiet area as a ringing phone free zone, if 
the metal paint would actually create a Faraday Cage effect, you could 
use these magnet paints, paint the walls, and ceiling (perhaps above a 
drop ceiling?) and create an area where cell phones would either not 
work or work very poorly, without installing anything that would anger 
the FCC.. 

Just a thought.
