Escape Pod publishes great sci-fi short story podcasts, unfortunately their podcast feed starts at episode 549. Fortunately archive.org has episodes 1 through 453 available.
This little ruby script converts the m3u from archive.org to an RSS feed for podcast apps to consume.
$ ruby m3rss.rb > rss.xml
Put that rss.xml feed somewhere your podcast app can reach it.
Here's one I prepared earlier on dropbox. The feed never updates, so feel free to put your feed reader into manual update mode.
