Store the serial number in a file in /Library/Application Support. Encrypt
the contents of the file in some way and node lock the information in some
way. Don't try to hide the file. I hate it when applications leave
undocumented hidden files in various places. I will often delete them when
I come across them.
If the file contains node lock info then copying the file to another
computer will not work. Encrypting the file in any manner, even a simple
one, will prevent most users from figuring out how to generate such a file
for another computer.
See this tech note for some info on node locking, or including info that
identifies a computer uniquely:
