The good news, new OpenNI drivers are available, possibly enabling Multi-Kinect support for skeleton tracking.
The bad news, the download links have changed, so till I update the links on my installation page and auto installer get them yourself at openni.org
Even worse, seems like the Kinect isn’t covered yet (only the PrimeSense reference sensor) so we’ll have to wait a little till those get released. Not sure if is possible to do a fresh installation now as the old links are gone.
Maybe stable release OpenNI with unstable release avin2 works? Ur on your own to try.
Also check the OpenNI google group for help.
