RSS Aggregator for UtahPolitics.org


I run a blog on Utah politics at UtahPolitics.org that has become quite popular here in Utah this political season. I'd love to add an RSS aggregator for other political blogs that cover Utah to the site. I found several tools for displaying a single RSS feed like the feedsplitter tool producing the yellow box on the right from my RSS feed for my discussion forum. What I want however is something more like Dave Winer's http://feeds.scripting.com/. Ideally it would read an OPML file given as an argument and present latest entries from the feeds in the OPML file according to some user supplied template. Anyone have any suggestions? Leave them on the discussion board
