Not sure if you caught the mention of this last week, but the Syndicated Client Experience Starter Kit Beta & Reader SDK was released last week.  This is a "a Starter Kit designed to make it easy to create rich, syndicated multimedia and content experiences which engage the user, from documents and photos to videos and podcasts."

If you've seen the Architecture Journal Reader, the Times Reader, or the MSDN Reader you're already  familiar with what this starter kit can do for you. If you want a rich presentation of RSS content (regardless of whether it's coming from outside or inside the firewall), it's definately worth a look.

You can find out more details on it here:
