At the PDC, whenever a session is too full, they have overflow rooms where they beam the presentation and a video of the speaker. This is a wonderful idea and it's very useful for people who would miss their favorite session otherwise. It's almost as good as being there since most of the sessions you sit far back and see screens of the speaker anyway. Even cooler, though, is that some creative folks began camping the overflow rooms. The idea being that the most interesting sessions (with some 'sleepers') will overflow and with only a few footsteps you can view the best sessions. Personally, I love it because I actually stand outside the overflow rooms and peer/listen through the doors-- bouncing from session to session. I'm much more interested in getting breadth over the cool tidbits than getting a deep pull into any one thing (probably the story of my life). When you sit in a session, you're a captive audience and you watch every second of people navigating their IDEs/demos/technical probs/etc. Just a moment ago I watched a session on Microsoft Research's thoughts for future synchronization/concurrent (e.g. RaceTrack, Cω, etc) while I also watched an interesting panel on the future of RSS (with Microsoft, Newsgator, etc). Now I'm waiting for overflow sessions to start for the next block. There's always the possibility that no sessions will overflow this late in the conference, but that simply means I can go and get a seat in any of the other rooms of my choice. I spent a long night talking to the Windows Installer and WiX development teams. More on all of this later.
