[mpich-discuss] How to make a non-MPI process to become a MPI process of MPI_COMM_WORLD?

Yes, you can use these on different nodes as well, but you need to run the hydra_nameserver somewhere and tell mpiexec where the nameserver is using the -nameserver option.  Use mpiexec -nameserver -help for more information.
