"BlogSieve ("Advanced Feed Processing for Atom, RDF, and RSS") is a new service that is fresh out and has potential for those wanting to mix RSS feed sources and recombine them in new ways:

BlogSieve is a web-based tool that creates new feeds by filtering, merging and sorting existing feeds. The BlogSieve engine accepts virtually every (valid) feed format, processed results are then exported into any feed format you choose

You can enter up to 5 feed sources (RSS URLs) as a starting point. The feature that Blogsieve offers that may maje it stand out from others, is that you can create a series of "filters" or search terms, so you are not getting everything from all 5 sources, but ones that match keyword criteria. It also provides output in 4 flavors of RSS."
