Hi,
We used to do all of our feed updates and uploading manually, but it was slow and tedious work. Often it would take us three to four days after recording to get everything setup correctly. When we decided to overhaul our podcast we also decided to create an entire automated UI from scratch. Since we don't use a CMS for the public facing web portal (we chose to design everything by hand to create a more custom feel) we had to do everything from the ground up.

Now we have a system that we can use to upload our podcast to our remote host, generate the iTunes feed on-demand, and control the security. In addition, we also added an analytics engine that tracks direct and referred (ones from iTunes) downloads on a per episode basis. The framework also syncs directly to our public facing site and allows users to see the show information, notes, related media, and anything else they need.

Anyway, that was just some background information, and we are currently finishing up the "podmin" framework. We were thinking about releasing it with an open source GPL license. It will be an installable PHP based package, and we are checking to see if anyone would be interested. Again, we are not charging anything for it, and are just trying to see if it would be something useful for the community.

Let me know what you guys think.
