FWIW, the Kinect SDK includes both C++ and C#/VB.NET versions, not just C#. Regarding the the upcoming commercial release, the FAQ implies that those commercial restrictions will be lifted, but of couse, the exact details aren't yet known: "Under the terms of the [current] SDK license, remember you cannot receive payment for your application, use your application for advertising, use your application to solicit donations, or use your application in your internal business operations. The commercial release, which is coming in early 2012, will remove these constraints." http://www.kinectforwindows.org/resources/faq.aspx http://www.kinectforwindows.org/resources/faq.aspx
