Interesting idea. If a keyboard has both wired-USB and some wireless technology, it's conceivable that physically disabling the wireless module(s) would be allowable. I guess there are two possible hurdles: (1) getting permission, and (2) finding a keyboard in which I can disable the wireless module without causing too much havoc with the rest of the electronics and/or with the firmware.
