If you get a "unable to write 'random state' message when attempting this, try looking for a file ~./rnd and see if it's owned by root. Delete this file and try again.

This spoofing seemed to work and confuses the heck out of existing wifi connections as defined in System Preferences -> Networking. Set before initially connecting. Hardware reset will reset to normal MAC.
