I have done some research on how to check whether a user is within a specific group.
good post:
Restrict my facebook app from other members. But allowed to those who are in a particular group
What I need is to allow users to create there own group but use the custom objects and actions I provide. The custom object and actions describe or give boundaries to the application I am creating in Facebook. I think this is done in Mafia Wars ( you only play with your friends maybe? ).
Let me know your thoughts!!!

After further review...
I am going about this all wrong. The platform, Facebook in this case, is designed to segregate users already. It's called being someone's friend LOL. If a user logs into my app they will be presented with all of they're friends who have also acquired or accepted the app too.
In other words I need to really read the Facebook API in it's entirety and pay attention.
