Suggestion: OPML Sources
Hi! I run a small project that collects and indexes podcasts feeds, up at 1.3 million active feeds (that has published episodes withing last 12 months), that will eventually be presented online as an open search engine for podcasts, a directory, with openness in mind (no logins, no memberships, RSS/Atom/RDF source feed URL) where you could add feeds one by one or bulk through OPML to your podcast catcher. I already have some spin-off data available and thought you might be interested to use it -- nightly builds of collections in OPML format covering assorted sources such a BBC, SR (Swedish Radio, I'm official source for this), YLE (Finnish Radio, similar role) and heaps more.
Interested? Peek at http://b19.se/data/
