I have a new download for those of you interested in creating an Apple style Enhanced Podcast on Windows.
This link will take you to the download page where you can get a zip file full of fun and frustration! You can currently interact with the software in two ways, command line or drop Enhanced Podcast configuration file (POD files) on the program's icon which will create the podcast.
It requires iTunes and QuickTime be installed on your PC (actually, only QuickTime 7.1 or later is required, but what fun is an Enhanced Podcast without iTunes or an iPod to play it). The documentation is minimal at this point but there should be enough for geeky media types to get something working.
