Re: Invisible files in copy protection

People generally have a very strong dislike for software-based
copy protection schemes, mostly because they tend to interact
badly with new system releases, new storage media, etc.
Besides, sooner or later, they can always be defeated if
someone wants to badly enough.

If you're going to modify something, why not modify the
MCL image itself? Another technique used by Quark Xpress
and others is to ping the network for another machine
using the same product with the same serial number.

If you're serious about copy protection, I'd recommend you try
a hardware approach. Several companies offer "dongles" that
plug into the ADB port, they do the job and are relatively
non-intrusive. Try Microguard (M.GUARD@applelink.apple.com)
