I know there is already a feature request for Kinect V2 integration, that would be very useful. I'm just doing some testing with it for the first time now. It works well with NI Mate, much quicker pick-up of the skeleton.
First thing to note is that it gives more joint position than the V1. Could you add a kinect V2 node with these extra OSC addresses please. (I know I could retrieve them manually but always good to have a built in node).
As you may know the NImate developer changed his licence/subscription recently and I asked him what plans he has for future support/development. Not much other than continued support for now it seems, the GL deprecation will probably effect some aspect of the programme in the long run too.
So how possible would adding the skeletal recognition into Vuo be? It would give us something to rely on into the future. (I read that you are considdering using Open NI in a thread somewhere).
