Program to Scrape Facebook Fan Page Email Addresses

Create a software that can extract emails from facebook fan pages of people who have LIKED or commented on them. This also includes event pages. If possible, I'd also love to have the telephone numbers. Also, I should be able to type in a niche and be allowed to automatically extract all of the most popular pages. Software should be multi threaded. Software should also extract names i.e. Michael Thomas, etc Software should be able to target according to countries Software should also be able to extra screen names (i.e. ICQ, Skype, etc) So for example, I should have a option (perhaps a search box) where I type Viagra. It will offer me option to define how many fan/event pages I want to grab of Viagra. So software will automatically grab all fo the Viagra pages (or how ever many I default to extract) And should save each fan page in separate file so that I know which fan/event page is which.
