My guess is that the MSR set up is a pretty large array of kinect like cameras. Pretty cool how they clean things up and connect through time to drive compression. Also think it is cool that they detect where hands and faces are and make the mesh more dense there.
But, the 8i folks have a demo on the web and MSR has a pre-canned video.
