The method I saw being used here at BYU in one of the Mac labs was sort of
hokey, but it would discourage the non-hacker types. All the files they
wanted to protect from tampering (would also work for copying) were made
invisible and left in the root directory. The students were issued a dinky
program that could be used to launch these invisible applications.

Anybody with MPW, ResEdit, FEdit, etc., could quickly and easily
defeat this setup, but it slowed their problems down enough to make them
managable.
