I didn't see an agenda for the working group meeting on the web.   Also,
the deadline for wg agenda submission has already passed (it was 7/15).
 This leaves Sorin and Tom uncertain about whether they will be able to

In order to address this impasse, I'd like to propose that we base the
meeting (probably without a formal agenda) on the high-priority items that
Chuck and I came up with and sent out on July 1.  Since those only amount
to 95 minutes total, there should be time to allocate both Tom and Sorin 10
minutes each for their presentations.   In order for this to work, all
presenters, and whoever winds up chairing the meeting, will have to be
