Hi Daniel,
   all IPv6 multihoming ideas are very theoretical today. None of them
is ready to use. Shim6 looks very good, but it requires support on both
a client and a server side. As you can guess, there is only experimental
support for some operating systems. Microsoft and Apple doesn't support it.

Well, BGP multihoming works today quite well. It's no different from IPv4
and is a perfectly viable technology.

to reiterate, if you are multihoming in ipv4, you likely have a pi
assigned prefix or one that you have permission to advertise from an
upstream. If you obtain a pi v6 prefix via the same channel you obtained
the v4 one it is likely that you simply advertise to 1 or more upstreams
and you are done. I have done this too good effect in three different
organizations that I've had the privilege of working with so far. I'd go
so far as to say that the experience was exactly the same.

A one possible solution I have found is based on a network prefix
translation (NPTv6 http://tools.ietf.org/html/draft-mrw-nat66-12). Using
NPTv6 you can do multihoming that is very similar to multihoming based
on IPv4 NAT.

You can also use thumb cuffs to suspend yourself from a rafter, but, I don't
recommend it unless you are into pain.
