I'm trying to enter the podcast generation so I can be cool and listen to podcasts on the way to work. I'd like to listen to BBC Comedy but there are a ton of barriers to stop me.

1) The BBC don't provide an RSS feed with enclosures for their comedy
Solution: I've written a screenscraper: http://www.thundermain.com/rss/bbccomedy.aspx

2) The BBC only provide the comedy in RealAudio
Solution: Use a Linux box to transcode the RealAudio to MP3:

#!/bin/sh
mplayer -playlist "http://www.bbc.co.uk/radio/aod/shows/rpms/$1/$2.ram" -ao pcm -aofile "$2.wav" -vc dummy -vo null
lame -f --preset voice "$2.wav" "$2.mp3"

3) Find a Podcasting client to link the RSS feed with the download script. This is where I'm stuck. I've yet to find a podcast client which will link the two together. Synclosure is the closest I can find as it has an external "handler" in the form of an action (Note to Synclosure: Your action script is Windows only because of the "@start" command) and in any case, Synclosure does not appear to differentiate between different podcasts with the same URL (ie podcasts with different checksums posted to the same location)

So I'm a little stuck. Can anyone help out?
