My only problem with multi exodusii files is that ExodusII_IO writes the mesh every time which is not a good idea when you have a huge mesh. 
I was thinking of HDF5 + xml files to point to the topology and the data i.e. write separate mesh topologies every time it's modified and point to the right mesh in each xml file.
