Batch schedulers and message passing libraries/environments are two totally different animals with different design goals.
Using MPI for inter-node communications is not going to gain batch schedulers anything extra, but the limitations, for e.g. handling master node failover, dynamic node removal/additional (yes, I know MPI-2 has dynamic tasks), etc, are simply too great to workaround.
