This is very badass, but who in the blazes still plugs their keyboard into their PC with anything but USB cables?<p>(Disclaimer: Yes, I know that there are probably still hundreds of thousands of legacy setups in constant use that are probably connecting their keyboards with PS2 cables. But if you're travelling and working in a hotel room, you're probably on a laptop, and if someone can hook up a remotely-monitored oscilloscope to your electric system and get away unnoticed, you're hosed anyway.<p>It's still pretty awesome, though.)<p>Also, this makes me wonder if the signal on wireless keyboards is encrypted. Do most of them use bluetooth? Is that safe against people dropping eaves?<p>EDIT: Ahh, I see. You can detect the signals wirelessly... my ignorance about electronics shines boldly through. The demonstration is very, very cool.
