You may be interested in the "Checkpoint" mesh format: https://github.com/libMesh/libmesh/blob/master/include/mesh/checkpoint_io.h
It is still XDR based... but basically just writes out the raw mesh as it sits on each processor and then reads it back in during a restart. Because of this you have to restart using the same number of processors as the initial run. It's the format we use for restarting in MOOSE.
