me, there are already a lot of cases where a tenant will use the same
address range to stamp out identical topologies.  It occurred to me
that we might even being doing this with our own gate infrastructure
but I don't know for sure.

We already have NAT serving as the natural divider between them and so
there is no reason to create another artificial way of dividing them
up which will force them to change their practices.  I've come to
terms with this since my earlier replies to this thread.
