i dont know why it's changing, but you can probably find your "old"
mac address in /etc/udev/rules.d/70-persistent-net.rules (or thereabouts),
in case you need to get back to your old address to avoid a need to pony
up for another 12 bucks today.
Anyone know how the kernel handles MAC address collisions? Since you
are at a DEFCON, its possible someone sniffed your MAC and is now
squatting on it to avoid $12 ponies.
