David,
Joe answered this pretty well. Especially the winning smile bit.
I wish we could elaborate on that a bit further ;-)
For the purposes of the discussion related the implications and effects of key rollover, I don?t think who is in charge/who provides oversight is particularly relevant. When we get to the point of actually changing the key, those questions become more important, but I don?t think we?re there yet (e.g., there are some that argue the key shouldn?t be changed ? if that argument wins, questions related to who?s in charge don?t matter).
Well, if any argument "wins", then that's a decision in the making and the question who is in charge to call for that decision and determine consensus isn't really part of the equivalence class "don't matter". I'll pause now, though. -Peter
