IMHO i like this idea. The simplest solutions are always the best , but
are you sure that this two idioms (iterators & pointers ) should be mixed ?
Does standart allow such iterators ?

PS: not too serious:
If  "anyone" implements iterator_traits for a smart_ptr, than
what will be the name for its iterator category:
"uninterative_iterator_category" ?
