I just can't wait to see stuff demoed in this. Techchrunch has an EXCELLENT write-up about this new technology, and you can read it here:

http://silverlight.net/The TechChrunch article is especially great if you want to get some overview over the technology. What is it, what can it do, who will use it, etc. Great stuff
UPDATE
Ummm.. scratch the part about WAITING to see this demoed. There's a bunch of demoes already up, and MS also made available a video showcasing Silverlight in action. You can find all this at the Silverlight page I linked to. After installing the Silverlight beta (free of course) and restarting IE7, I watched some high-def movie trailers as streams in the browser, including a cool interface on the top that let me choose whereever I wanted to be in the video with not only a progress bar, but little screenshots of the video at those points in playback.
One of the demo videos I just watched for a bit showed off another impressive video editing app running completely in IE7 in Windows Vista. This thing featured thumbnails of videos that had full motion live previews whatever video was moused over, and the guy demoing showed off how easy it is to edit two clips and then combine them into a single clip (the latter action being done with a single drag/drop action).
I'm impressed already. Can't wait to see what's next
