I can't make it this year either, so I've been scouring the web trying to find a feed. Thus far, this is the only one I've found:

I think they're in testing phase at the moment; I keep seeing a lot of shaky-cam and people slinging cables around. I'm hoping it'll stabilize once the event gets underway.
For an audio feed, there's also BMIR:

Hope these help!
EDIT: I just opened the webcam page again and right now there's just a picture of the ticket. So, who knows. I'll keep it open in a window regardless for any playa snippets they might have.
By the way, does anyone know what happened with the Current TV broadcast? I went last year so didn't notice that there was none. Looks like 2008 was the last broadcast. Any ideas?
