I think you're right Robert.  I can get my types to serialize fine
with the boost::binary_*archive archives, but not with the mpi ones.
It's strange because I can get it to work for send, but not recv.  I
get an exception related to unregistered type.

Indeed if I go and manually serialize every message pointer to a char
buffer vis binary_oarchive, and send that via boost mpi, and manually
deserialize on the other side from char buffer via binary_iarchive, my
program works.

I'm unsure what exactly might need to be instantiated in boost::mpi though.

Thanks,
  Brian
