Michael,
As I have answered before, the "new stuff" functionality would be much more powerful as a general service than stuck in one package, or worse, each package rolling their own version of "new stuff". I would love to see this done, but we want to make sure it can be used with other pakcages as well as forums. It then could show a view of new items on an entire site.
The unanswered questions function seems to be forums-unique and is a great idea.
