Hi,

I intervened today after the MP-TCP with single-homed hosts to mention
that this is very close to what we're doing in Homenet with Source-Specific
routing (SADR) and IPv6.

The general approach is to distribute multiple IPv6 addresses to hosts,
one per ISP, and to route towards the right edge router by looking at the
source address.  No further protocol changes are necessary -- we just send
plain RAs with multiple autoconf prefixes; I believe that something
similar is possible with stateful DHCPv6, but I'm not a specialist and
would rather not make a fool of myself.

We were delighted to find out that MP-TCP works out of the box with this
style of multhihoming.  No changes are necessary -- you just put MP-TCP on
the client and the server, and magically your traffic starts flowing
through multiple links.  I almost cried.

If you'll forgive me some self-promotion, our work was described in detail
in
