The article noted this: "They faulted cost pressures on keyboard manufacturers for not making keyboards more snoop proof."

So if this is true, at least it appears that new keyboards could be improved to block eavesdropping.

It would probably be pretty easy to kill the EM emanating from the keyboard. If all the circuitry was surrounded by tinfoil and the cable had better shielding, it'd probably cut the radiation a lot. If anything, i'd bet its the cable that does all the radiating? I'll have to think about that one a bit.

Its totally badass though. I kinda wanna go home and build something like that. Probably harder than it looks though.
