Wireless Soundbard?

Does anyone know if a sound equipment manufacturer has come out with a wireless sound board that eliminates the need for running cables into an auditorium? In other words, the actual sound board would on stage with the equipment and you would use pc software to send signals to it telling it which adjustments to make on the board. Seems like a relatively simple concept that would avoid the need for running a snake into the auditorium.

So wireless in the sense that you CONTROL it wirelessly by another computer, not that it is a stand alone thing that nothing is connected to?
