Perhaps you can personalize it further than just by show. I've often wished there was an easy way to subscribe to Nina Totenberg's legal reports. I enjoy them, but I don't want to subscribe to all of All Things Considered to make sure I don't miss them.
Well that was my point. I was assuming you can do some sort of curated-feature situation. Whatever customization the app offers, the output is basically just a list of NPR episodes and links to a server hosting them. If you wrote a server-side application that generates custom RSS feeds per-user, managed using a web panel (or a plugin for existing podcast clients), you'd essentially get the same feature set, but it would be compatible with your preferred audio backend.
