[boost] Is there any interest in a smart pointer facade class?

Is there any interest in a smart pointer facade class? I have in mind a class, that works similarily to boost::iterator_facade for developers of smart pointers instead of iterators. template < class Derived, class Pointee > class smart_ptr_facade; Recently I wrote two smart pointer classes, and felt the need for such a class. I would like to write such a class, and if everything goes well, perhaps add it to the Boost library. Regards Krzysztof Czainski
