With traffic engineering hacks, it could be done. For sure, not plug&play.

We did some experiments with kind of NAT64, other context. Such a hack could be used for path with v6 to GW, and using NAT64 to remote v4 node. Difficult, maybe ready after full scale v6 deployent....

Multi-stack MPTCP with one v4 subflow is possible. During movements and with multi-SGW, additional v4 subflows could be added. Question is when MPTCP should set up a new flow (using just another port, same v4 S and D addresses). Also way too complex.

Conclusion: let's build v6-only multi-path multi-homing for now. And see how to support v4 later on, if needed.
