I've tried my application with MPICH2 and OpenMPI only. The readline stuff works in OpenMPI as long as I don't start my application with mpirun. It does not work in MPICH2 irrespective of whether I start my application with mpirun or not.
My application starts on a workstation and spawns slave processes on cluster nodes. The application provides an interactive command shell and provides some GUI functionality using X.
Do you know how bad is the MPI_Comm_spawn issue if I don't start my application via an mpirun?

It is likely that Open MPI won't work properly in this situation -- Open MPI provides basic I/O forwarding. I don't know if curses-based or readline-based applications will work through our forwarding.
Do you know if this application works with other MPI implementations?
When I run my MPI enabled application via mpirun, my application command-prompt looses its readline editing capability. I was wondering if there is workaround.
