They only work with connections on the same meter.

Yes, provided that the power in the two rooms is passing through the same 
meter.  I gather that surge protectors can sometimes interfere with the 
connection (if it is required to pass through them!), but I have no problem 
with them.

A colleague who has seen my setup and knows more about electricity than I do, 
says that it is just remotely possible that a little could leak out beyond 
the meter.  But it seems to be at least as secure as WEP, probably more so.

FWIW, they also do a wireless access point, which can prove useful if you want 
need a wireless booster.  Plugging one of these in might well prove cheaper 
and more effective.

I'll happily answer more questions, provided that I know the answer ;-), so 
please ask if I have not answered fully enough or you have more questions.
