Can we add that also for unique_ptr Reference Implementation?

Other smart pointers can benefit from a templatized pointer type also,
like intrusive_ptr:

template<class T, class VoidPointer = void *>
class intrusive_ptr;


With Boost 1.34 boost::pointer_to_other<> and generalized get_pointer()
utilities intrusive pointer could support different pointer types.

I'm also seeing if a shared memory/memory mapped file shared_ptr<> is
possible using templatized pointers, but the lack of polymorphic
operations in shared memory would require an additional deleter template
parameter and an additional allocator template parameter to allocate the
reference count. Too much?

With so many smart pointers, I'm certainly confused. What's the
difference between unique_ptr:

and move_ptr:

Do we need scoped_ptr in future C++ standard if unique_ptr has all
needed operations? Or it's too dangerous for a scoped resource pattern
because of the release() operation?
