I'd point out something here, that might not need pointing out
explicitly, shim6 MAY only work if both sides of the conversation
decide to use the protocol.

So, if your small office situation (dsl and cablemodem connected and
shim6 enabled) starts/tries to do shim6 with a 'content provider' site
that has PI space and doesn't know from shim6 (some content providers,
akamai, use strange kernel tweaks/os-tweaks and likely won't support
shim6 'features' early on) doesn't shim6 isn't going to provide the
multihoming and failover and TE (perhaps) it should be providing.

I'd venture to guess it'll be a whole lot less useful than even it's
proponents wish it would be, with the situation above in mind atleast
