I have been planning on doing a wireless rift and its working great.
Heres how.
First part you need is :
http://www.ebay.com/itm/ASUS-WAVI-2-Way ... 0719651643
Its expensive, but really good. It transforms usb and hdmi to a wireless signal.
I can detect no latency, and asus claims the latency added is below 1ms.
Its power supply delivers 12v at 2 amps, but I managed to run it at 10 volts 0.7 amps.
Razer hydra pulls about 5v 0.5 amps and Oculus Rift itself pulls 5v 0.7amps if I am not mistaken.
Thats a total of 13 watts and should run fine from these babies:

three type 18650 3.7volt batteries with 4Ah , total amount of voltage about 11.1v
You can use a voltage regulator if you want to make sure it stays at 12v but I tested it below that and it ran fine.
The Oculus Rift however needs 5V 1000mah according to the box, but will pull less.
I am using this to convert the 11.1 to 5v, but you can use a standard car charger that converts from 12 to 5 volts.

In addition to Razer Hydra and the usb from Oculus Rift, I am using a good old Hillcrest Labs FSM-6 sitting horizontally on the edge of the rift controller box.
Why?
Because it instantly acts as a mouse when connected, so turning in real life will turn your body/walk direction in most of the games and demos for Oculus Rift.
No more controlling walk direction with mouse or stick. It really works

Theres actually room inside the asus wavi box for plenty of batteries and a small passive usb-hub if you need more ports.

My multimeter is not working for some reason, so I wont be able to make a video of how to assemble it all until tomorrow. (I want to triple check so I dont fry my gear)
But more pictures are coming and also a video.
