How about the machine population? How about self-replicating systems? How about geography-based address allocation, to go away with global routing tables? How about InterPlaNet, such as LEO routers, solar power satellites, controlling industrial production on the Moon and elsewhere? I don't expect IPv6 will last much longer than IPv4. And that's probably a good thing.
15 trillion /48s. Let's assume that the RIRs and ISPs retain their current level of engineering common sense - i.e. the address space will begin to be really full when there are about 25% of those /48s being routed... that makes 3.75 trillion /48s routed for ten billion people, or 375 /48s per man, woman and child. (Or about 25 million /64s if you prefer.) At that point, IANA would have to release unicast space other than 2000::/3 and we could start again with a new allocation policy. I am *really* not worried about this. Other stuff, such as BGP4, will break irrevocably long before this.
