Can anyone tell me if the Planet aggregator software can be used by audio and video podcast feeds?

“Planet” refers to a server-side software that aggregates multiple feeds (usually written or created by people who’re interested or actively participating in a project or topic) into both an OPML format and a website that presents, on the front page of the Planet website, all the most recent posts to the included blogs by date and time of submission.

I’m wondering about this because, if the <audio> and <video> tags and Ogg Vorbis/Theora are to be supported by bigger players like Mozilla in the next version of Firefox (or so it is rumored), then I think that it would be a good idea to sort out how a Planet would handle feeds that display media formats in a way that would be friendly to both text-centric feed readers (Google Reader, NetNewsWrire, Bloglines), that will simply show you the link to the source file and an embedded player, and audio/video-centric feed readers (Miro, Juice, Amarok) that will play the media within the client.

Whether such a development will spur acceptance of Theora and Vorbis as default podcasting media formats for FOSS developers by is another question altogether.
