A question of faith

Jeff beats me to it, relating particular religions to particular identity systems.

I'd add to Jeff's list the following:

• Passport - any of the monotheistic 'Big 3', e.g. Judaism, Christianity, Islam with their whole 'No other gods before me' shtick 
• UProve - The Mormons. Stop preaching at me that my soul is lost, I'm doing just fine thank you.
  
• XDI - Rastafarianism . I may not buy into the premise, but it looks like a good time.
  
• VRM - Buddhism. Not a religion per se, more a philosophy of personal growth and empowerment.
