FWIW, I caught the tail end of the stream and the quality was fine.
I'm looking forward to being able to watch the entire recorded session when it's available. If you're at all interested in the issue, I recommend that you watch this and make up your own mind on it.
Edit:
The recorded video is at http://infodocket.com/2011/11/16/live-video-stream-sopa-stop... I used VLC to view it.
