If I understand what you mean by "serialized directly", that is what I 
am trying to do.

This way it works.
This is the meaning of "ar & BOOST_SERIALIZATION_NVP(this)" in the code 
at the end. It is semantically meaningless, but it generates a reference 
to the object with the pointer of the right type. Hopefully it does not 
do anything bad when deserializing.
