I'm a Brit living abroad, and guiltily use one of the (probably illegal) methods already mentioned to watch the BBC - I feel bad, but I just can't do without it!
One thing to know, it's completely okay to listen to BBC radio from anywhere in the world, http://www.bbc.co.uk/iplayer/radio. There's a sports station for the Olympic Coverage - Radio 5, and I also heartily recommend Radio 6 for music, and Radio 4 for excellent speech radio, including news, documentaries, comedies and dramas.
