Sly RSS Feeds are Huge, and in a big need.. There's reasons why they are not available.... Not many understand RSS and before I really dove in to code some RSS projects, it was mind boggling to figure it all out..
I did a few scripts for sponsors, and they were great, but the lesson learned was running good feeds was a time consuming task and the content was literally destroyed 24 hours later... So therefore not much development gone into providing good ones..
But with that I can see the huge power in it.. Problem is the tools are not there to provide RSS feeds on an advanced level, Well until now that is.... I just releasing RSS CMS (Sponsor Edition)
I have a Power User version in the works, that should take care of the entire scenario of user needs.
If you use feeds, please check out the link I posted above, and take a test drive of what it can do, then inform your Sponsors to hook it up
I am here to help all get going, and further develop this wonderful tool
