	Serial numbers can be encrypted *WITH SOME OF THE CODE*
in a way that makes removal non-trivial. Just taking two disks
and comparing them is of little use if you DO NOT KNOW THE METHOD
OF ENCRYPTION. While we're at it, why use only one method
of encryption???? Making code copy detectable for any reasonable
method does increase production costs though...
