Can you explain what the underlying requirement that is satisfied by having
such a criteria in the transfer policy? Given that regions came about out of
administrative convenience and efficiency in distribution, it is interesting to
see them take on significant meaning in a post-allocation environment...

become rather popular in the near future (i.e. at the point in time when
ISPs will no longer provide static addresses to new business customers)
