This is exactly why I assumed a billion multihomers on multi6. But this
has very little to do with the growth of the global routing table in IPv4,
since there is no way current protocols can accomodate these numbers of
multihomers.

If you want to, you can certainly talk BGP to customers like this. I'm not
sure how many BGP sessions one router can accomodate, but it's probably
hundreds. Of course flapping will be a problem and nobody in their right
mind is going to accept those announcements.

If there is a market for home multihoming (mh²) then I'm sure someone will
create a service where you can get a fixed IP address and easily create
tunnels. If the tunnel endpoints are at the closest regional exchange
point, the RTTs should be pretty good.
