	This topic used to come up occasionally (although in regards to 
shutting down wireless access in exam rooms). We used to point out that
wireless (and only our wireless at that, as we couldn't legally block 
ad hoc access points without jamming which is illegal in Canada), blue tooth, 
and cell (which it looks like this device may fix) are only the alternate 
vectors we could think off off the top of our heads. As it would have been a 
signifigant amount of work to modify the wireless network to do this, we 
(at least up until I retired) had resisted doing so. We expect there are a lot 
more vectors that students could think of and this is trying to solve a policy 
problem with technology which rarely works. Think also about PDAs, watches 
with memo pads (for storing cheat sheets) and who knows what else. 
	That said this device would be a relatively painless way of doing some 
of the job (although I'd be sure to point out it isn't fool proof), and thus 
may be a good bet. Consider though that in most environments it is going to 
complain about phones in the hall way outside the exam room / lecture theatre 
as the RF happily leaks through most walls.
