Don't laugh. The three letter Government Agency for which I work fills all the USB ports, etc., with epoxy. Wireless networking is NOT permitted and the buildings are shield to prevent RFI from leaving/entering the building. Additionally, security personnel "war-drive the perimeter of all buildings to ensure there is NO 802.11 traffic. Also,if I remember correctly (I'm at home now), the extra network port and parallel and serial ports on my PC have been filled with epoxy too! The infrared ports and such usually have a shield permanently glued over them too! LOL
