I had stated previously that "This simply doesn't work on a windows 7 64 bit machine."  I have since  installed the SDK on a Windows 7 64bit desktop.  I can now say it actaully does work and it is pretty cool.  I am still having trouble getting it to work on my laptop though.  I suspect there must be some sort of software or hardware conflict.  If I figure out the issue, I will post it here.  I dont know if it is related or not but the working computer lists only 1 device icon for the Kinect in the "Devices and Printer" view.  The non working environment lists four icons, one for each component (camera, device, hub, and USB composite device).
