Thanks James. "Back in October, we announced a new Microsoft video delivery technology called IIS Smooth Streaming. In a nutshell, this approach combines both client (based on Silverlight) and server (based on IIS) components that, together, deliver scalable media experiences up to 720p+ over the internet using the plain old HTTP protocol. We have had a preview of the technology running over at http://www.smoothhd.com courtesy of our CDN partner, Akamai. We also added support for encoding to, and previewing, the new format in back in Expression Encoder 2 SP1. Today we are announcing beta availability of the IIS Smooth Streaming component completing the picture and enable users to test the technology end to end.. You can download the extension over on the IIS Site. "
