Hi Tony,

Barring the single-homed scenarios that are also relevant to the
multi-vendor multi-homed case, I think we can make that assumption. At
least nothing else jumps out at me. We can also eliminate the
single-vendor multi-homed non-server case since the addresses there
can be carved from the vendor's PA allocation.

I'm not sure what you mean by point solution.

If one solution is known for a problem and despite years of attempts
no other solutions are found, should not that one solution gain
functional equivalence to an axiom?

It's hard to make meaningful progress if the group has to keep
stopping to re-prove that yes, there really is only one known solution
here and no, that alternate approach didn't pan out, and no that
clever idea won't work either, and yes it really sucks that we're
stuck with this but we are.

Just so I'm not the one saying so. ;)  You'll notice that one of the
solutions it doesn't negate is TRRP.
