Wireless controllers

Is there any known way to make wireless controllers?

For the Neo? It's possible no doubt. No one really stepped up to make one though.

Edit: You could probably make one using a 10 button transmitter/receiver. Maybe find the pinout on the receiver and connect that to a hex inverter so when the line reads high it send +5v to that specific line.

Maybe.

Sigh far to technical for me. I wish someone would look into this as i'd pay to have almost evrey system i own converted to wireless controllers.
