You know what this means...

Now we won't be able to hack into other stumblers, cuz we're all using 002c DEAD BEEF.

btw: I've had this happen on a network before in the olden days. Two 10BT cards with the same MAC address (inconceivable!) It causes all kinds of connectivity problems for each card. But a total pain in the butt for the IT department to track down.

Unless they have an IDS, of course.
