I'm investigating how to setup multihoming for IPv6 over two DSL lines

When you talking about "two DSL lines", I assume this is mainly for
office / residential environment to have redundancy and/or increase
In this environment, BGP exchanges with uplink ISPs for multihoming
usually is not an option. One reason maybe cost, another reason maybe
ISP doesn't like to setup BGP with a DSL customer. At least in my
case, reason #2 always prevent my customers to setup BGP with uplink
As Seth pointed out SHIM6 is still an academic exercise, my
experiences to resolve this needs at this moment is leveraging NAT66,
as what we did in IPv4 world. I use FreeBSD+PF and Juniper
NetScreen/SSG to do NAT66 in several different locations, and they all
works as expected so far.
Some people don't like NAT especially NAT66, but to be realistic that
does work, and works well in terms of providing redundancy over two
DSL lines for office / residential needs.
