In fact, this reason had not occurred to me!  I have always assumed that
the reliability reason for multihoming was to continue operation when
their own interface goes down.  That's quite different from a concern
over network partitioning, elsewhere.

(Geographically distributed multihoming for large organizations is a
different matter.)


In any event, let me again stress that I am pursuing this kind of issue
in order to distinguish near-term, narrow concerns, versus
longer-term, general concerns. The hope is that this distinction can
allow initial solutions to be simpler.

From my own sense of the net and from the responses so far, I believe
that a host can maintain an address pool based solely on a simple list
of the destination's addresses. That is, for the near term, the
combinatorial complexities of considering local/remote address pairs can
be deferred. Of course, the implications (that is, the limitations) of
this simplifying assumption need to be stated.
