I would have a slight preference for const unique_ptr because it  
doesn't have swap or reset.  It is *really* const.  Beyond that it  
probably wouldn't matter much as I find myself typedefing most of my  
uses to something more descriptive within the context I'm using it,  
and easier to type.  E.g.:

typedef const unique_ptr<node_pointer, node_allocator> node_holder;
