I'm maintaining an API that scrapes the WAP version of the forums. I bumped my thread about it
https://bitcointalk.org/index.php?topic=154131.0The API is two parts: one is the actual scraper, which creates Java objects out of the pages but has no other logic. The second project is the actual API which runs on Google App Engine and contains some intelligence about what to scrape, and when, and how, etc.
Of course there is the question of "what about when the forums upgrade" but the way things are going it doesn't really seem imminent.
