The December PC Tech Journal has an excellent article entitled "The Futility
of Copy Protection" by David Small, which discusses numerous protection 
methods and how companies/people have gotten around them. Ignoring the issue of
whether software should be copy-protected or not, I think from reading the 
article you can  1) Get an idea of what methods haven't worked so far,
2) Get an idea of how to copy-protect your own software using an existing
method, and 3) deduce that no matter what you do, the best you can hope for is
to keep your product copy-proof for 3-6 months.
