The only solution is, IMO, to let multihomed sites have multiple prefixes inherited from their upper ISPs, still keeping the sites' ability to control loads between incoming multiple links.
And for the basement multi-homers, RA / SLAAC makes this much easier to do with v6. The larger-scale / more mission-critical multi-homers are going to consume an AS and some BGP space whether you like it or not - at least with v6 there's a really good chance that they'll only *ever* need to announce a single-prefix. (Ignore "traffic engineering" pollution, but that doesn't get better or worse). Regards, Tim.
