turns out that the wireless driver they offer is like a wireless modem that communicates with the hardware as well as any other wireless drivers you may have and can synch as many powerheads with as many drivers as you can afford and they will all work congruently.....
pretty cool stuff although you do still have a power cord from the powerhead as well as from the wireless driver...
