Z100 does stream over the Internet, but I'm not sure if they'll be broadcasting anything from this (I think they usually just broadcast interviews with the Jingle Ball performers as they're doing their sound checks). I went to Jingle Ball last year, and they did show footage from the All Access Lounge on the video screens between performances.
I have nothing to do that day until dinner time, so I'll definitely try my best to go.
