Get this. If you want to watch MSDN webcasts now, you have to authenticate that you have a valid copy of Windows.

Why? Why can't I watch them if I'm running something other than Windows? No, I'm not advocating piracy, and I understand that most people who watch the videos are developing from a Windows box, but what about Mono developers?

This seems a bit extreme to me. It's fine to make me validate I have a genuine copy of Windows to get updates, but this is taking a good technology and applying it in the wrong place.
