The only way this will work (as far as I can tell) is if you completely hack and rewire the buttons and use the controller from a standard keyboard OR the more feasible solution would be using an IR version (I believe someone mentioned one of these) with a universal IR reciever. I don't think you'd be able to use it like a normal keyboard. Each key would have a special function. Though I may be wrong.
