Strictly the answer is no for MPI-1 applications, as the two parts don't
share a common communicator (their have seperate MPI_COMM_WORLDs). 

Shortly the PVMPI system will be released, that will allow independent MPI
applications to communicate via modified inter-communicators even across
different MPI implementations using the normal MPI-1 point to point
communication calls.

Supported versions will include: MPICH, MPIF (and maybe LAM and SGI MPI)*
