Dear Robert,

thanks a lot! Do I understand it correctly, that I could easily create
my own serializer for std::shared_ptr by just (de)serializing the
contained "raw" pointer and wrapping it into a std::shared_ptr in the
case of de-serialization ?

>From what I can see, I do not have to care about the reference counter
inside of the smart pointer. An object that is serialized and
de-serialized somewhere else has a life on its own there. In my case,
the objects are sent back later, but from the time of arrival back in
the home system lead a life of their own.

Best Regards,
Ruediger
