Actually, there's a whole IETF WG (MPTCP) dedicated to creating a TCP
Multipath option which would function appropriately with hosts holding
multiple PA addresses. There's a whole other group dedicated to
improving SCTP to a point where it's credible as a TCP replacement.
There's even a third WG (MIF) trying to work through the source
address selection implications of a host that sits on multiple
networks.
