Feature parity with iTunes tags and compatibility fallback

I can't remember whether this was mentioned in the latest Podcasting 2.0, or if it was in Adam's appearance on Buzzcast, but I think it's worth discussing.

What do you think of replicating all the features of the iTunes namespace?

The point for this would be to let app-developers support only a single namespace that has all the features, but then fallback to the iTunes tags if the matching Podcast tags aren't present.

<itunes:episode> would have an equivalent <podcast:episode> for the episode number. Similarly, <itunes:title> would have <podcast:title> for a podcast-app-specific title.

Yes, that's definitely the long-term goal. I think we talked about it Friday on the show. That's where I'd like this thing to end up. Just down the road a ways after we fry bigger fish.
