Implementations/suggestions for Multihoming IPv6 for DSL sites

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.
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.
I haven't found any commercial product that supports it, but you can use
an implementation for Linux (map66
http://sourceforge.net/projects/map66/). Assembling map66 with some
other scripts (to detect link failure) you can have what are you looking

I wonder if that kind of knowledge can be learned in any Cisco course
today. I don't think so.
