This is probably wandering a little off topic, but I can't see how anyone
could justify a substantial increase of code size on every honest customers
Pilot just to frustrate crackers.
Given the code size of the average Palm application, the similarity in
structure of Palm applications and the frequent references to resources,
I'm sure any cracker with a modest knowledge of Palm applications and the
68K would be able to break any complicated scheme an author cared to try.
