to be fair, there are 3 options for multihoming today in v6 (three sanctioned by the IETF, not ordered in any order, not including discussion about goodness/badness/oh-god-no-ness of these) 1) multiple addresses on each device, one per provider 2) shim-6 3) HIP (still in development, as I recall)
4) Obtain PA space and do what you're doing with v4.
5) Obtain PI space and do what you're doing with v4.
(4) is problematic because filtering long prefixes in v6 seems to be more energetic than it is in v4. (5) is problematic if you don't qualify for PI space.
Note, however, that the bar for (5) is VERY low if you are multi-homed. I would not be opposed to lowering it even further, but, there does not at this time seem to be community consensus to do so. Owen
