The Kinect SDK has just released a Beta1 Refresh. The update applies a number of driver enhancements including stability fixes to prevent crashes, including those that appear when a PC goes into sleep mode. The update also supplies runtime enhancements around refinements to a number of APIs, improvements in time-stamping, and the removal of non-functional APIs. The documentation has also been overhauled as well, and new SDK samples have been posted. Download, BUILD, and enjoy.

I will be doing a Kinect SDK talk at South Florida SQL Saturday ( http://www.sqlsaturday.com/79/eventhome.aspx ). No Kinect doesn't have anything to do with SQL, but what the heck.
