    Just a random thought: If natd(8) were taught to change its default
    alias address on the fly (it's just a single variable,) then the
    desired effect would be achieved exactly. That's because any session
    already having its own entry in natd's aliasing table would use its
    old alias address kept in the entry. BTW, one could switch between
    even more than 2 external connections in that manner. And that's
    just a step away from session-aware load-balancing with natd(8).
