I've just tried for the first time the killer combination of;

1. Expression Encoder
2. The plug-in for Expression Encoder that lets you encode a video and publish it directly to Silverlight Streaming
3. The plug-in for Windows Live Writer that lets you automatically publish a Silverlight Streaming application into a blog post.

Together, these 3 produce one of the coolest things I've seen in quite a while - I can just take any old video and get it onto my website in the quickest, easiest manner with a full Silverlight application.

This is very, very slick.

It's so slick that I thought I'd use Camtasia to record a quick screencast of me uploading this particular blog-post so you can see exactly how slick it is. Not 100% sure how well this will come out because I was a bit "hasty" in the transcoding...
