OK, I'm in heaven! I just discovered that SourceForge has the ability to serve up RSS feeds on any project in their system. Project-level RSS feeds seem to center around news releases for the project, and you can choose among a few formats (like with or without full news release text). In fact, they have a complete writeup on all the RSS feeds available and explanations/FAQs.

I was also impressed with the way their documents were laid out, being able to jump into any section of the document, like the table of contents or a specific topic like "What is RSS?" I think this is a great idea, and I will try to include this feature in any content management system I eventually build.
