But one won't need to upgrade a Tier 1's hardware to support shim6, as

shim6 is:
1) not baked
2) not helpful for transit as's
3) not a reality

Not baked is absolutely correct, and not a reality follows readily from that, as viewed by an operator.

I'm interested in (2), though. Shim6 is not intended to be a solution for transit ASes. If you're an ISP, then you can get PI address space and multi-home in the normal way with BGP.
*IF* you're a big enough ISP. There are (a few) ISPs with few enough customers that they'd have to "exaggerate" plans to get the same level of multihoming that they do with their legacy IPv4 allocations...

Also, are people going to consider accepting longer than /32s from their direct peers? (not for global transit, just peering)... in this case I'm thinking about those networks who do inconsistant announcements at various NAPs for "in-country" and other reasons.
