You might be able to take a user's data to establish their profile, they consented by using your application after all. But I don't think you can export their friend list and use it to invite them to your new social network.
Either way, I think Facebook could find something in their ToS to shut you down if they feel like you're stealing their users away. There was a recent article about a tool from Power Ventures that allowed you to login to multiple social networks and aggregate the messages, friends lists and what not. Facebook seemed to claim it was a violation of the ToS because they were accessing account data using "automated means."

FriendFeed is part of Facebook though?
