I just came to this idea before reading your post :>
Small changes to move_ptr implementation will make it work:
    move_ptr move()
        {return move_ptr(*this);}

    template <class U>
    friend move_ptr<U> move(move_ptr<U>& p)
        {return p;}

I admit I like more Howard's way. Anyway, definition of private cctor is
now required:
      move_ptr(move_ptr& p)
        : d_(p.d_), v_(p.v_),
        { }
