Right now and through the 4 days of the con, GenCon (pretty much THE con for everything geek) is having livestreaming of the convention. And my best friend from high school/evil twin (or maybe I was her evil twin we never did clear that up) is one of the two hosts of the filming. You can watch the video feed at the gencon website or on the front page of
http://www.neoncon.com/ Also she is sending twitter updates at username: d10again.
And here is the press release that gives all the details.
