Wi-Fi-proof paint

An American company says it has successfully tested wireless-blocking paint. EM-SEC Technologies, in a release last week, said its "Coating Solution", applied to a test facility, had successfully protected "wireless devices and other electronic equipment".According to the company, "a one-time application of the coating creates an 'electromagnetic fortress' by preventing airborne hackers from intercepting signals".EM-SEC reckon this would be useful for corporate offices, boardrooms, server and computer rooms, and R&D labs. It seems that wireless nets can be operated without trouble inside a painted building or room.
