Good one. I don't know the exact implications of nofollow, but I think it might be that if google considers the destination to be legit that it will add the url to its crawl queue without giving it any 'pagerank juice'.
Only a googler could tell you for sure though.
I've seen google ferret out results that were never linked through the toolbar or some other mechanism outside of the regular crawl process. (in that one case the toolbar was my only possible explanation, or it was through analytics).
