External Data Provider and more RSS options?

[jpfdeuce]

I'm inolved at FanHome.com which is set up in six different categories for different sports and general discussion.

My ongoing problem is that I'd like to create one feed for each of these categories and their numerous forums within them (for example -- category: baseball and all the MLB teams as well as some general baseball forums). One can note that we have the categories listed as forums (http://baseball.fanhome.com for instance -- scroll down and you will see the forum is closed for posting) in order to have a more visible list on the main forum index at http://www.fanhome.com/forums.

So has anyone ever fooled around with the syndication of their vBulletin and added additional categories or sub categories and exclusive feeds to several forums at once?

Or perhaps, even something more in depth such as the posts themselves having RSS feeds? You can see this in action on blog softwware as well as on Wordpress.org and their help forums.

thanks
