First of all, thanks for the different ideas that were presented!  I just
might change
my scheme.

To follow the coding challenge, I have a few follow up questions:

1)  If I do use the backed-up preferences database, I assume by the comments
that there is no way to have it automatically deleted if the app gets
removed.
Can anyone correct me?

2) My original thought was to allow another grace period if the app was
re-installed.
Can I detect the first use of a program since installation?  (Remember: this
question
is posed to discuss the coding issue, not the scheme [ I was serious about
changing]
;-)

Regards,
David R. Britton
