Matt, 

Please see http://aspn.activestate.com/ASPN/Mail/Message/1456023
(especially the non-quoted section at the bottom).

I've been waiting for more feedback about the issues discussed
there. So far I'm leaning fairly strongly away from the "just do the
right thing" approach and toward the register_shared_ptr<T>()
approach on the "don't pay for what you don't use" theory.
