re: David Snearline's note

To provide for the student using the campus computers and perhaps one
own at home, the solution is to use a small ADB-type device that plugs
in easily.  (Such a device is on the market today, toward the $50
range and can be in series with the keyboard or mouse or at the end of
an ADB line.)

Yes, I would never support disk level protection -- too vunerable.

A better solution would be to use something built into EVERY CPU.  I
believe that every ETHERNET card has a UNIQUE address.  Some products
use this number as a protection against unauthorized use.
