I took a quick trip to France this afternoon to sit in on (yes, unfortunately, it was all virtual) a great panel discussion between representatives from Google, Six Apart, MySpace, Facebook and Microsoft. Of particular interest to me was the focus on openness in a distributed universe.  I'm particularly fascinated by the balance between the Facebook approach and the approach by some of the other players who have committed to participating in various layers of the open stack.  I'll comment more later if I have the time.
