And I don't see multihoming adoption in IPv6 being anywhere quicker
than in IPv4, so: where is the problem, please? We'll have about 1
route per ASN... so even when exhausting the 16bit ASN space, this
will be only <65k routes. And when will this be, extrapolating active
ASN growth? 2010? 2015?

Call me a retarded idiot, but I have a really hard time seeing any
_practicle_ problem with "1 ASN == 1 IPv6 prefix" at all.
We'll run out of 16-bit ASN space much faster, and have to transition to 32-bit ASNs.

Otherwise, by making the policies a bit stricter, we might make do with 16 bit ASNs, or at least make do with them much longer.

I don't like the idea myself, but there it is.
