It seems to me this is related to Moose's new MultiApp capability: solving
different systems on subcommunicators (with the interaction between the
systems handled outside of PETSc)?  It may be that the cleaner approach is
to have the subsystems (their solvers, rather) use prefixes to set their
specific options.
Would that be enough?
