endpoint independent mapping and filtering enables address referrals

independent mapping and filtering.
I don't disagree... Lets say that endpoint independent mapping is
one half
of a solution. We need another half: either a "simultaneous hole
punching"
mechanism, (and/)or endpoint independent _filtering_...
Maybe that was our misunderstanding: Yes, we need both, endpoint-
independent
mapping /and/ filtering. But re-read my email; I in fact talked about
both.
