As I've commented in a number of threads, you have a few options for watching today's game online if you can't get yourself in front of a TV, or if you're in the SEC-area 'dead zone.' For those of you whose ISP supports it, you'll have access to a high-quality stream of the game on espn3.com. There is also a link at channelsurfing.net to watch the game. I just tried it, and it works already. It is definitely someone's ESPN2 feed, most likely in an area where our game is on ESPN2. The video quality is average to poor, but it's better than nothing if it's the only option. justin.tv doesn't list live events until they're happening. Here's the link to a search of live UCLA events, which should hopefully find results come game time.
If you're in an area or situation where you don't think you'll get to watch many games online this season, bookmark/favorite the justin.tv search and the home page of channelsurfing.net. One or both of these will likely have most if not all of our football and basketball games - and I used channelsurfing.net to watch most of our baseball and softball games this spring as well.
