For $100,000, you get a lot more than 2000 additional customers
worth of routing table entries. Further, let's look at the cost of
that uniquely after we subtract out the cost of upgrades that would
be required anyway due to other factors (forwarding plane capacity
requirements, routing table growth from other causes such as TE,

Yeah, but, once he has done the latter, you're still stuck with the
of carrying his route, so, I'm not sure why you think that's a gain.
The effort, btw, that started this discussion was trying to extend the
multihoming policy down to /24 instead of /22. I don't think anyone
is advocating (in the v4 world) that we open up additional bits for
non-multihomed end users.
