VLC supports playback already at least on Linux. I believe Microsoft is just using the same name to describe what they are doing in SilverLight but it isn't based on Apple's spec. I'm sure this has a lot to do with the broadcasters supporting it already for the iPad. Some of them have done so since before launch. The new Apple TV platform will surely build on top of that and I'm guessing you will get to see the same iPad CBS app running on a TV.
