Render Kinect data in a canvas element using NodeJS+Socket.IO (skip to 21:50)

I was at Art&&Code at CMU where several people were playing with this idea, including the original libfreenect developer, his was getting close to 25 fps if I can recall correctly, was using a lot of MS voodoo.

The code is on github: <a href="https://github.com/sreuter/node-kinect-fun/" rel="nofollow">https://github.com/sreuter/node-kinect-fun/</a>

Is there any more background on this and how it is done? Awesome, if there would be a ready to go library for this
