I take your point.

On the contrary, I think it is important at a BOF for this topic to be
brought up, if ONLY for it to be CLEARLY ruled out of scope.

ROLL would have to be rechartered to work on it; this is not to say that th=
is
could not happen, but rather to say that even if we were meeting, discussing
it might be out of scope anyway.

Having said that, this thread is most welcome.

I abhor "side meetings" --- either have a proper BOF in a room, or get a
bunch of beers is my opinion.
