I'm not sure which reference counted Smart Pointer you're using. If you use
the boost smart_ptr, its already has serializaiton done. If you want to add
serialization to your own Smart Pointer, you can look at how it was done for
the boost smart pointer - now there are two versions so you have lots of
ideas available.
