shim6 (was Re: IPv6 news)

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.Since shim6 requires changes in protocol stacks on nodes, my impression has been that it isn't a _site_ multihoming solution, but rather a _node_ multihoming solution. Is my impression incorrect?
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?If my impression is correct, then my feeling is that something else is required. I am somewhat skeptical that shim6 will be implemented in any near term timeframe and it will take a very long time for existing v6 stacks to be upgraded to support shim6. What I suspect will be required is real _site_ multihoming. Something that will take existing v6 customer sites and allow them to be multi-homed without modification to each and every v6 stack within the site.
