Think about it. Dozens of people are sitting there with laptops. How hard is it to get a laptop in with a 3G card along with some Shoutcast or similar audio broadcasting software and to simply turn on their laptop's microphone? There's so many reasons this needs to be done and should be done: 1) Very very low chance of getting caught by the Apple keynote security guys. No having to hold a camera, no having to position it right, and you'd look just like anybody else in the audience fiddling with their liveblog. 2) Very very low bandwidth needed. The stream could easily be done with a low chance of having it go down due to traffic congestion. 3) MANY people can easily listen to the original audio stream and easily restream it through another means without worrying about capturing video. 4) People at work could just LISTEN to the audio stream on their phone without getting caught! Imagine just turning on an app on your phone and listening to the keynote with a single earbud, live! Multitasking at its finest! 5) It's much better than pressing F5 on a liveblog to read stuff if there's no covert video stream. Somebody make this happen tomorrow!
