Fred,
If we are able to reduce the routing table size by an order of magnitude, I don't see that we have a requirement to fundamentally change the routing technology to support it. We may *want* to (and yes, I would like to, for various reasons), but that is a different assertion.
There is a fundamental difference between a one-time reduction in the table and a fundamental dissipation of the forces that cause it to bloat in the first place. Simply reducing the table as a one-off only buys you linearly more time. Eliminating the drivers for bloat buys you technology generations.
If we're going to put the world thru the pain of change, it seems that we should do our best to ensure that it never, ever has to happen again.
That's the goal here? To ensure we'll never have another protocol transition? I hope you realize what a flawed statement that is. We can't see into the future. However, assuming that IPv6 is the Last Protocol seems a bit short sighted. If we get 20 years out of IPv6, that will be just peachy. Of course, if we can't get PI address space for enterprises and real multihoming, there won't be any real IPv6 deployment. Lots of (possibly illegitimate) IPv4 trading and NAT, but not IPv6. These aren't nice to haves. Even if it shortens the life of IPv6, that is an acceptable trade-off. IPv6 is not the Last Protocol.
