Thanks. What I was wondering is if there is a way to do the same copy
protection in FreeBSD, where I could store the data in the same place on the
drive where the user cannot access it.
Normal, average users yes. But as the above stated... dd will let me (as
root) get to any part of the disk I want. If you're users don't have root
access, then just make it a normal file owned by root, chmod 400.
I seem to remember some software put it's license key in the boot sector
(this was way back when and I might be not remembering correctly). But
even that can be read using dd... not sure how I'd do it with windows,
but I'm sure it's possible.
