I may not necessarily agree with the technical specifics of Heiner's msg, but I do think the msg made a good point: to provide useful input into RRG London agenda, we need to first have a clear goal(s) for that meeting.
Just volunteering a talk for whatever latest results multiple individuals have achieved may or may not help RRG to move forward.

So what do we as a group want to achieve?
Reactivating RRG would be the results of identifying that goal (the group would march towards that clearly articulated goal).

Or maybe the goal of London meeting could be to identify/clarify the goal?

(in that case, Heiner's msg did make one position statement as an input, for the group to consider)

PS: I must admit that I have NOT had time to go thru the 40 or so RRG msgs since Vancouver IETF, ignore my comments if the goal had been clarified earlier (other than "reactivating RRG").
