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.
Is there any more background on this and how it is done? Awesome, if there would be a ready to go library for this
Nothing super fancy really, reading kinect data with a native program then pushing it out over a server via websockets to the browser that renders it using canvas.
