I'm not under any delusions about getting such a change to std::shared_ptr 
into c++0x.  That doesn't preclude something like this being added to boost 
though, under a different name (I'll call it "generalized_shared" for the 
moment).  Then boost::shared_ptr could be implemented as

template<typename T>
class shared_ptr: public generalized_shared<T*>
{...};
