I was thinking like a SysAdmin, not a developer. I've had plenty of
experiences where nodes aren't communicating b/c someone hosed up the
machines file, .rhosts file, and other stuff like that. I guess it's not
really relevant if your focusing only on developing an MPI app, not not
administering a cluster.
