I think this is a very important effort. But we probably need to think
of it in terms of the proposed DBOUND work rather than tell people to
try to discover the zone cut through heuristics.

Heuristics are OK as a transition strategy but I don't like them as a
long term fixture.


The problem I have with the current DBOUND discussion is that it is
being driven by a use case I think is completely unhelpful. There are
no occasions where I think it is safe to share cookies across domains.
So trying to come up with rules for when it is safe is a losing
proposition and so is trying to develop a technology to meet that
goal.

DNS Privacy is a much better defined concern and one that we have a
good chance of addressing with something like DBOUND.
