I am working on a large university project and one of the aspects is: "See who of your friends from other social networks are part of this network". This is a GPS like software that uses your cellphone as unit and is to aid you and your friends to locate each other in new ways. What I need is to ask the users for their email (and/or password) to other social networks to enable the users to see which of their friends are part of this gps network. Is there any way to retrieve the emails from Facebook App? - or make a request for the emails as the "user" rather than a application?

I am using Facebook Toolkit 2.0 from 6.nov - trying to make ASP.NET site that accomplishes this task.

Thanks for your help

No, Facebook does not let you retrieve too much information about friends. The user class contains the info you can get back from a call to API.friends.getUserObjects() but it only contains basic information (names, pictures, public profile info) and not emails.
