I've been following @harbars on twitter and knew he was over in the 'States doing the Microsoft Certified Master Program, but reading through the other list of attendees just goes to show what a unique experience that R2 session was - most of R2 (as was R1) of the Program were Microsoft folks.
So even more congratulations to Spence on the achievement.
Check out the MCM Blog posting on it, and the SharePoint team posting.
PS: Did I tell you that I used to work with Spence ? ;)
