There is just an raw and very simple experiment with a mocap data transmission from the Kinect to the Unity3D trough an simple UDP connection (sockets).
Server side: MSKinectSDK + openFrameworks + ofxNetwork.
Client side: just couple of lines of native c#
It works with blender and python too, I check it ;)
