Then how *does* that fail then?

Different programs, different requirements.
All in all, the outgoing interface needs to be able to reach the
destination, if not all slave servers are on the same network,
you would need to be able to specify a outgoing-interface on a
per destination basis.  It will get very hairy then.
So far, the assumption that the primary address, had been good enough.
We can always extend functionality.
