gainly: Okay, first of all, calm down. No need to get all worked up about it

The iPhone 4's facetime feature will probably work exactly as advertised, no setup required. How? A database of FT-compatible devices based on phone number. Every FT-capable device has a phone number, and that's a perfectly reasonable unique identifier.
A couple things to note:
1) No setup required means no additional work needs to be done. It is assumed that you already have your friends' phone numbers in your address book. Therefore, it doesn't matter what you NAME the contact, just that the phone number is correct. So unless you're adding a new contact, there really is nothing that you have to TYPE in advance. aka. Zero-setup.
2) No one ever said the iPod touch or iPad or anything else was getting Facetime. Until we hear otherwise, iPhone 4s are the only FT-capable devices in existence. So again, phone numbers are a perfectly reasonable unique identifier for this purpose.
I don't know why you're getting so worked up about it. Does it really matter how it's being done on the back-end? Nothing about it seems "impossible" to me.
