I have also noticed that BBC Radio 5 Live (available over the interwebs) has audio commentary for matches that doesn't seem to be blocked online (either for geographic or contractual reasons). Yesterday's Liverpool vs. Tottenham match was one of them, and I was streaming it to my iPhone while driving.
Anfield Cat was perhaps even more fun with only audio to rely on.
Usually the local BBC radio stations (and Absolute Radio) are blocked so the clubs can sell the commentary to subscribers, but it seems that Radio 5 Live has a different arrangement.
Just thought that I'd pass that along for the fellow desk jockeys and paper pushers who might want to listen to a game in the afternoon every now and then.
