They do stream all the sessions online, along with the I/O extended sessions around the world. I think Google do a good job of making the actual material available...although I will accept that is no substitute for the networking/experience you get from being there. That's one reason why the Extended events are quite good, as you're generally able to meet a wide range of people. To be honest, I think the best solution would just be to lottery it, but then again I suspect if they were to lottery it there'd be a lot more people entering than attempting to get tickets in such a short space of time.
