The one use I could think of us to make your internal network
independent of your ISP. Right now, if you change ISPs, your network
prefix changes and your whole network has to be renumbered.
I read about it in the following article earlier this year.
http://www.theregister.co.uk/2012/03/31/ipv6_sucks_for_smes/
I'd be happy to have it pointed out to me how the article is wrong, but
it seemed to point out the ugly corners the IPv6 folks don't talk about.
What you need to multihome is either BGP or NAT. Exactly as in IPv4.
Nothing has changed. The only new thing with IPv6 is that there's more bits.
However, with more bits you have the possibility of using a "nicer" form
of NAT in that statelessly maps one prefix to another:

And here's a draft with more info on how to apply it to multihoming:
