A similar but tamer method I've used is to encrypt the user's name 
along with the registration key file.  When the software starts up,
the splash screen says "Registered to Joseph Schmoe" along
with the registration number.  The idea is that this will discourage
ordinary users from simply passing their keys around.  The key
encryption and validation must be good enough to prevent casual
crackers from figuring out how to create their own "valid" keys.

Of course, all this assumes that somebody wants the software
pretty bad in the first place.  
Haven't figured that one out yet... ;-)
