I think your choice to abandon implementation of MPI_TYPE_STRUCT is pretty reasonable, but at the same time, it is possible to pass some "simple objects", which are instances of a final class and contains references, through MPI interface. If this special case is implemented, for example, array of complex numbers can be sent via MPI native interface. Methods and results shown in Section 5 is very interesting. If you have chance, please compare these results with the one with improved RMI routine described in Paper [17] (in the bibliography of your paper).
