Getting baroque with the Pipes... this one fetches the 'Audio on Demand' feed for a given BBC radio station (after passing it through resourcefix to add the missing XML declaration), filters it for shows matching a given string, adds a direct link to the iPlayer, looks up the RealAudio link using a nested pipe (this is a bit gratuitous) and squirts out an RSS feed (or any of the other formats that Pipes produces).
