@waldomac**....."What I wish to do for this client is do the best that is available to make it as difficult as possible."

**Well put...and that is about all you can do.  I think it would be best to enlighten your client to the fact that his works may be stolen if placed on the net...if someone is so determined.

Also, identify to him the things that you (and he) can do to make theft more difficult....at least that way you both have a common understanding at the outset.

Good luck with the project.

In youth, we learn....with age, we understand.
