I agree that a larger time slot is very important to discuss all of the
relevant facts and approaches we have.  I for example would like an hour
or so to discuss group messaging approaches.

The approach of continuing the work taking place in Germany is very
problematic..  Many of the key people will not be at the Germany summit
because 1) it hasn't yet been announced and 2) its too late to get any
kind of travel approval 3) the cost of a germany summit trip being 4k
places it outside the boundaries of what most U.S.  companies are
willing to fork out.  OLS is a far superior venue for any kind of
cluster summit meeting since extending travel for 1-2 days is pretty
approachable for those already attending OLS.  I suggest the cluster
meeting at OLS be a standalone meeting, perhaps based upon some report
out of the results of the germany meeting instead of a continuation of
that effort.
