I am currently using sshfs to mount both OpenMPI and my application on the "other" computers/nodes. The advantage to this is that I have only one copy of OpenMPI and my application. There may be a performance penalty, but I haven't seen it yet.
For a small number of nodes (where small <=32 or sometimes even <=64), I find that simple NFS works just fine. If your apps aren't IO intensive, that can greatly simplify installation and deployment of both Open MPI and your MPI applications IMNSHO.
