There so many reasons why this is a good idea: You won't get caught by Apple's security if you just turn a microphone on A video feed is likely to fail on you anyway, while an audio feed is less problematic. Most people won't be able to see video because they're working or whatnot, so this will give them the chance to slip in an earphone at work and listen along like an oldtime radio broadcast. Less bandwidth costs involved. People would crash your feed within minutes. Would also help people get info over 3G whereas video would be tough. There's more options for audio broadcasting solutions than there are video. It's better than nothing if you can't sit and watch the liveblogs. If one of you keynote attendees are reading this or know somebody that is attending the keynote, do the audio feed, seriously. Video is always a fail, but this will work.
