I like the idea of a password based on mac address or serial number.
It has some inherent security compared with a default password.
Surely it could be done as a script? The system wakes up after a
reset to default and says to itself - "No password - create a new one
from the serial number with this script. There, that's better. Now
I'll allow wireless to be activated." Then all copies of the OS
could be the same.
