It does look great, but I doubt I'll ever use it with a Hog3. My wing(s) is/are always next to the board, so a USB-cable is sufficient. Why take the risk of eventual problems or slowdowns by using wireless USB?
Well, I'm an operator/programmer co-operating with LD, who is also a close friend of mine. We always try to seek new ways work. In many situations LD takes care of the balance on conventionals, usually front and sidelights. Nice way to take care of this is to give him a playback wing (when he is sitting in audience). Of course one possibility is to give a wireless HogPC client with wing. Though sometimes just a few faders would be enough and keeps things simple.
