In case of non-cooperative sysadmins, can't you just have instances of MPI installed on your accounts on the slaves? I presume each slave has a Sage installation (with OpenMPI), so this probably means you need to create symbolic links to appropriate directories, and/or perhaps setting LD_LIBRARY_PA
