Great question. I've been dying to use Kinect as well. I think things left off where the newer version of Kinect platform is not supported.
Support for this would open up doors to interacting with screens through outside windows, interactive waiting rooms, etc. It's an open market for many interactive products.
Sorry I'm no help, I've not ventured to try it because I didn't want to try to work with unsupported platform. But I'm going to follow this discussion because I share the same interest as you!
