They are supposed to be unique *per machine* - you can have two nics on
the same machine with the same MAC although this is rare.

Never seen a Sun ;) ?
On SUN sparc stations, _all_ the nics have the same mac-address, based on the system-ID.
So you can swap Ethernet boards, while your MAC remains the same.
