I confirm that on the reception side, the class name is not found in the
archive (debugging this).

typedef templateclass<arg> myclass;

On the sending side, I have BOOST_CLASS_EXPORT_KEY(
namespace::namespace::myclass )

I don't know why it is not sent down the pipe.

Could someone pinpoint where I should see the class name sent in the mpi
archive code?
It is obvious where for input but not for output.
