This new technique was mentioned on the list before CanSecWest:

And this is the technique:

"Presenters at the CanSecWest security conference detailed [on Thursday] how they can sniff data by analyzing keystroke vibrations
using a laser trained on a shiny laptop or through electrical signals coming from a PC connected
to a PS/2 keyboard and plugged into a socket.

Using equipment costing about $80, researchers from Inverse Path were able to point a laser on the reflective surface
of a laptop between 50 feet and 100 feet away and determine what letters were typed."
