What if a program was HALF copy-protected?  What if software came with
a facility to make itself work only on a specific machine?

(A few months ago on this newsgroup I saw a lot of suggestions on how
to do this, including checksumming the ROM.)

The software can be installed easily FROM THE ORIGINAL DISKS onto
any number of machines any number of times.  The original installation
disks may be copied by DOS.  BUT, once installed, the software cannot be
copied from the hard disk to a different machine.  (At least not easily.)

Here's the motivation.  We accept the fact that someone who owns the
program can install it on more machines than he/she should.  We try not
to make the owner's life difficult.  But no one can copy the program
without the owner's permission.

This would be helpful at computer labs where many people use software,
but only a few people are responsible for the computers.  This would
neither help nor hurt an individual who buys software for personal use
at home.
