Let me add one thing:

While I think this kind of feature should not be mandatory for bindings 
(and cannot be part of libdbus-1), it can be provided as convenience 
functions by those same bindings.

So, after thinking for 60 seconds, I did come up with a way of doing that 
very feature in QtDBus. It would require, just like boost::shared_ptr, 
that you relinquish control of your object to the framework.
