Another thread from the BBC - keystrokes can be captured over powerlines!

Snooping through the power socket
Hand on keyboard, Eyewire

Power sockets can be used to eavesdrop on what people type on a computer.

Security researchers found that poor shielding on some keyboard cables means useful data can be leaked about each character typed.

By analysing the information leaking onto power circuits, the researchers could see what a target was typing.

The attack has been demonstrated to work at a distance of up to 15m, but refinement may mean it could work over much longer distances.

Nice article but nothing new :p

Seriously: any "metal connector" can be used to get your data, with no difference is it a power cord or heater pipes. There is only the question: is it cheaper than using a crowbar on user? ;)

BTW I remember reading once that some guys retrieved screen data using telescope pointed at screen's light reflection from the wall on the opposite side of the room. That is something to think about.
