Also, did you test whether what you want to do works if you use binary archives, to store and load the object?

This was happening at a stage where I was not consistent in the sending broadcast with the receiving broadcast.
Just to double check, I assume that it should be possible to:
1. send with mpi::broadcast( , const base_pointer, ) and receive with mpi::broadcast( , const base_pointer, ), granted the derived classes have been exported with BOOST_CLASS_EXPORT_KEY in both translation units.
2. send with mpi::broadcast( , const derived_pointer, ) and receive with mpi::broadcast( , const base_pointer, ), granted the derived classes have been exported with BOOST_CLASS_EXPORT_KEY in both translation units.
I am doing 1. and 2.. In both cases the receiver throws "class unregistered" even though the BOOST_CLASS_EXPORT_KEY expands correctly in both sender and receiver(slave) translation units.
Yes, the idea is that these should work. To see where the problem is I had asked you:
