Now that I think about it, it would be really standup of Apple or someone to provide a webservice that would take an Apple iTunes Podcast link and do the translation to return the standard XML feed that drives that particular show. That way, people that implement various products that act on the feeds could the iTunes link and do the conversion themselves. It would certainly save me a lot of time from doing that process I related in the previous post. It really sucks, and I'd be happy to never do it again.

Update: Andrew Clarke has this working as a client side python script. It works!
