I didn't have to rewrite my iterator, just use it. I believe you are pointing out ways to make it easier to rewrite a naive recursive solution so that it can be re-implemented as an iterator instead.

By "Try to go the other way" I meant (at least in part), try to use jdporter's callback interface (as-is) in a situation where an iterator is needed.

Though, I don't even understand what you linked to yet so I still consider what I did to go from iterator to callback to be "trivial" compared to what you are proposing as "not too difficult". (:
