This is an absolute necessity. Without an RSS feed, there's no easy way to listen to this on a Podcast app. I for one do not bother with any podcast that doesn't have a feed.
TIL, you could subscribe to podcasts via RSS on iPhone via the Podcasts app. For those who also didn't know, you go to Library and hit edit at the upper left to get an "Add podcast by URL..." button. Interested to check it out, thanks!
