Cracking wireless keyboards

The recent demonstration of a wireless keyboard sniffer

is pretty slick, and it is pretty amazing how weak (almost nonexistent?) the encryption is. One thing that I haven’t heard mentioned is the possibility of injecting packets into the keyboard stream, to take control of the system. Maybe at that point it might be easier to just sneak over to the system and type on it?

By the way… anyone have a spare 27MHz source and a mixer? Its a shame I don’t have easy access to that equipment anymore :-)
