580 ex 2 or Q-Flash T5D-R (For 5D Mark 2)
I don't think there is even a port on it to allow for a pocket wizard to be attached, at least not that i have seen. I have looked at this system and can't bring myself around to the price and bulk of the system as you have to buy a battery to hoist around too which is another $450 or so. I would like to try it however but being on the go i can't imagine it being user friendly, so It disqualified itself. Same thing with their new. Good deal for $400 as it is $1200 on B& H
The Qflash TTL X5DR transmitter model has less power but same external power supply and mounts right on your shoe mount without an adapter, $770 without battery and an additional $665 for a battery which is another 2.5 lbs.
