I'm sure someone else has thought of the term already, but in the spirit of Waypath's meta-weblog services, I thought of a generalization: metasyndication services. Eventually there'll be quite a lot more information flowing through RSS, the majority of which might not come from weblogs. But there will be meta services that aggregate, analyze, and distribute that content and even operate on larger scale, complex dynamics of those feeds.
Heck there's only a few references on Google to the term "metasyndication" and nothing for "metasyndication services".
