Listen Up[1] (free version[2]) team is working on integrating it with gPodder.net[3] which, unfortunately, seems to be folding under the new load[4]. It's down right now, actually, and I don't remember their webUI but the desktop client[5] is nice so if you want to manage subscriptions from your computer, that's a way to do it. Not currently but in general. This is what I'm going with anyway.
