Well look at this… The Silverlight Team has launched their own podcast. The first episode of the podcast is on IIS7 Media Services 3.0 featuring Silverlight Senior Product Manager David Sayed and IIS Senior Program Manager Chris Knowlton. This is the tech that powers Smooth Streaming for those that didn't know (like me).

They offer two formats: enhanced (with pictures and stuff) and MP3 (just for audio players). They don't have a feed for just the podcast that I have found as of yet.
