This is what we call the "multi-protocol" problem, and is the next major
enhancement, scheduled for starting to work on this summer, along with
dynamic process management.  Currently there is not a way to do this in
MPICH.  Our plan is to implement first a "two-protocol" version, in which
every process has access to its "native" communication protocol (CM-5 switch,
shared-memory, SP2 switch, whatever) and also to TCP for communication with
the rest of the world, both using MPI.
