How unique is an Address Book ID?

Hi All,

I'm very curious to know if the Address Book unique record ID is
guaranteed (or at least very, very likely) to be unique not only in my
local Address Book database.

That is, how likely is it that two Address Book records will be created
with the same ID:
- in the same Address Book database,
- on the same machine, and
- on two different machines.

I'm perfectly aware that AB is meant to be a one-user, one-machine
database, but _if_ I was to move or share Address Book data between two
machines, what are the chances that two records would collide?

thanks for any input on this
