I'm jealous of Mac folk

I'm pretty envious of my Mac friends for being able to use the Apple Podcast Chapter Tool. It's a slick command-line utility that binds XML metadata describing links, images and segments within a podcast in order to create enhanced podcasts. Granted, these only work for iTunes 4.9+, but it's a cool feature I'm trying to bake into my new broadband channel, which includes video podcasts.

Hopefully, there will be a Windows version or at least some equivalent utility hack.
