This topic comes up repeatedly in sci.crypt. Google for it.
The general consensus is that it is a waste of time.
A determined hacker will compromise any copy protection
system and once the system is compromised an infinite
number of copies can be made. That is a single compromise
is fatal to the system.

Microsoft has spent a ton of time and money on the issue and the best
they can do is produce updates that "break" compromised copies that
download them. Unless you are planning on spending more time and
money than microsoft, make it easy on legitimate users and hope your
software is worth pirating.
