Maybe web scraping then? It would not be so hard to make a focused scraper that scrapes the friends of anyone using the app.<p>Edit: I did a quick test and at looks like I can see the friend list of many users that is not in my immediate network as long as I am logged in to Facebook. It should then be easy to use something like Perls WWW::Mecanize to make a scraper that log inn and scrapes the profiles you want, as long as one do not need so many that Facebook detects and banns you.
