I just looked more closely at this, and it looks very interesting. With their input box, it looks as though I could just take 16 channels from the mix bus on my DDX3216 (or the direct outs) via ADAT; it would work similarly with an O1V96, etc. So only one box to buy, plus the individual personal mixers. The mixer itself looks to be better set up for running wireless IEMs since it has L/R line outs (not just headphone out).
Now I'm curious to see how they implement their digital snake. Hopefully, this will be something like the ADA8K, but with remote control trim (and input level peak meter info sent via Cat5). And it would be best if it were scalable in groups of 8. I wonder if it will require an X32 to control, or if they will inlclude an FOH box as an option to those wanting to interface with other desks.
