Many of these modules aren't on the radar of the average developer. Mostly because of the crapload of awesome (CoA) that keeps coming out of the IIS team. IIS7 is the #1 reason to get on Windows Server 2008R2, IMHO. I've long been singing the praises of IIS7. Of course, not everyone uses Silverlight, and lots of folks (myself included) have iPhones and iPads.
The general idea was to show folks that it's actually pretty easy to setup Smooth Streaming for Silverlight. Earlier this year I posted on Installing and Setting Up and Encoding for IIS 7 Smooth Streaming and Silverlight.
