As everyone's surely heard by now, iTunes 4.9 with podcasting support is out. It has a fairly complete directory, but with very little metadata on each podcast.
Apple has published a document with some RSS 2.0 extensions to fill in that missing metadata. I'm going to begin work on implementing those specifications in the WordPress RSS script ASAP, because I want my podcast to be usable within the iTunes directory sooner rather than later.
My question is: is anyone else working on this, or does anyone have an interest in it? If it's easy to do, I'll wrap up the extensions in a plugin. If it's not, I'll just hack the PHP and share the changes here. I've never written a plugin before, however, and my time is extremely limited, so I may ask for help on the packaging-and-polishing part if anyone's willing. Thanks.
