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.

The big gap in the multi-homing story for v6 is for end sites, since  
those are specifically excluded by all the RIRs' policies on PI  
addressing right now. Shim6 is intended to be a solution for end sites.

Are you suggesting that something else is required for ISPs above and  
beyond announcing PI space with BGP, or that shim6 (once baked and  
real) would present a threat to ISPs?
