Everyone can *read* /Library, but only admin users can *write* there.

My recommendation:
1) Give the user the choice of "Register for all users on this Mac"
and "Register for me only"
2) If they choose "for all users", then save the registration under
"/Library" (asking for admin credentials if required), and if not,
save the information under "~/Library".
3) Then, when your program looks for the saved registration
information, just use the standard search paths provided by
NSSearchPathForDirectoriesInDomains, and use the first one
encountered.

In this situation, an admin user (Mom, Dad, a Lab administrator, etc.)
would register it once, choosing to register it for all users, and
nobody else will ever be asked for registration information.
