Hmm... This could be a potential mini LUG project. On the other hand, it might be a bit small. I might just work on it myself.
I've created a perl (originally bash) script that calls mplayer (or program of your choice) and plays whichever radio station you selected. Selection is done using a command-line argument at the moment.
22nd October 2006 - Version 0.4 - Revised to bring the links up to date, and clean up the Perl.
27th May 2004 - Version 0.3 - Rewrote the script in Perl. :-) I like Perl.
26th May 2004 - Version 0.2 - Added $PLAYER_REAL, $PLAYER_MPEG and $PLAYER_WMA variables, so that different programs can be called for the different formats. I then realised that mplayer does all three, but whatever. I also added several more radio stations, and some comments.
23rd April 2004 - Version 0.1 - Added $PLAYER variable, so that you can change which program the script calls.
8th March 2004 - I created this script, fishing the URLs out of the BBC website. I don't actually have the original version, but it's no great loss.
