yes, we are aware of them. Infact the AC3 is what will be needed for the MC2 module for Einstein. Yes, the lights can be adjusted in up to 3 zones. And yes they can be hypersynced. You cannot adjust the full range of Einstein with this combo, nor can you hypersync with Einstein very effectively due to the short flash duration. Please read this thread for hypersyncing:
viewtopic.php?f=8&t=67 I do not think (though I may be wrong) you do not need the AC9 or AC3 to hypersync. You need a TT trigger and any Pocket Wizard reciver. In fact, you could probably use a TT transmitter as a go between for the camera and CST, then use our recievers on teh lights and still get "hypersync". The TT transmitter is only reading when to fire and passing that along to the CST. This also works to shoot in Live View with a Canon DSLR.
