Don't ask my why the organisation didn't publish this, but you can follow the Conference LIVE via streaming video and the quality is *awesome*. Speakers use a microphone and they're mixing the camera stream with the computer display at the right times.
The stream should play in VLC, RealPlayer and Quicktime. Just copy the following URL and
VLC: copy link and in VLC -> open stream -> RTSP -> paste link
Quicktime: select Open URL
realPLayer: select 'Open'
