I fourth (fifth?) the overseas concerns.
If they do cancel the overseas streams I vote we mirror all the main bbc stations output to mp3 and bitorrent the lot.
Wack a couple of servers running freeview cards on constant record, cutup the files by show time, seed and enjoy.
I actually do this but with http for recording certain shows to listen to on my mp3 player while abroad, no worries about dodgy connections, nice resumable download.
