Hi Doug,

> How do you define "mildly?"


I would derive it:  overall, we need to come up with a routing architecture that grows the table no more than 9%/yr.  Looking at the roles within the topology, which roles grow more than 9%/yr?  Certainly single-homed end-sites do.  Dual-homed end-sites would also seem to do so.  Top-level ISPs do not.


> I think the "best" answer is obvious, find a magic solution to the routing table problem, and give everyone PI. Since that's not likely to happen, we need to figure out a way to give as many people PI as possible.


I'd suggest that a scalable routing architecture is a higher priority than giving people PI.  While PI is convenient, not having routing is simply fatal.


> BTW, "the issue" with PI is not just multi-homing, it's also portability. In my conversations with folks about this (going all the way back to when I was at ICANN and talking to serious people about how to get IPv6 deployed sooner), enterprises that have PI IPv4 now won't even consider IPv6 without PI.


TANSTAAFL.

Except for a few early adopters, transitioning to IPv6 is going to be a hassle and not free.  Most people will not do so unless they absolutely have to.
