Keykeriki v2 (yeah version 2) is the device. http://www.remote-exploit.org/?p=483

It's keyboard only right now (and microsoft keyboard for attack). As far as range, it won't be much more then 20 to 30 feet. That isn't based on the device, it is based on the hardware in the wireless device. They have a really low power transmitter. The total range will probably be 2-3 times the range stated on the device. More then that, and there will be to much signal loss to be useable.
