[comp.sys.mac] copy protection schemes

hi.
I am inquiring about the copy protection schemes i've seen on some software
where you have to insert a key disk to use the program after it has been
installed on the hard drive.  (This protection scheme is on practally
all MIDI software for the mac).  I was wondering if this type of 
protection is easy to implement...(is there something I can add with
resedit easily?) ...or can I move the copy protection scheme from 
software that has it to my own software so that you have to insert 
a key disk to use it?
I'd appreciate any help on this. Thanks in advance.
