RSS Feeds and XML - Extras

Anyone using these features?

We use Small Business Server and have an RSS feed of the schedule sent to a web part on sharepoint portal services. The program names link to corresponding info on the public web site.

Also, I have a yahoo widget running the rss feed on my desktop.

I'm especially interested in a way to generate charts using the xml data that can be manipulated and posted on the web (basically a "see our stats" kind of site) and using a content management system to allow producers to supply their own program information and establish program blogs (something like drupal or broadcast machine).

Thanks!
