I have to say that I was very impressed with how the oauth session went. There was minimal presentation and maximal discussion, and the discussion was not interrupted until it started getting circular. But, I suspect that this is a reflection of the fact that there's some substantial disagreement about not just narrowly-defined issues, but some architectural models that people are working from, that there's a very large number of interested parties, there are time pressures and expectations from external bodies, etc. The discussion would have been lively no matter how the meeting was managed. But, I thought it was very well-done. The challenge is how to have meetings that productive when there are far fewer interested parties, fewer disagreements, etc. It may be the case in some instances that if it's going to be nothing but presentations there may not be a need for a working group to meet at all.
