I would say _supposed_ to be unique.  Surely some cheapo manufacturer 
has recycled addresses from their old ISA card days.

Back in the mainframe days, admins used to always set the MAC addresses 
of devices on the token rings, since the MAC address was used to bid on 
which node managed the ring.  I have seen people fat-finger it too.
