As an aside: The particular technique used in the OP (resource objects) is actually not transparent. If you send the object handle to another machine, it will have an opaque handle that it can't do anything with apart from storing and sending around. However, if the other machine sends it back (and the resource object hasn't been deallocated in between) it will be the same as the one that you sent.
