5. user then loads your app onto Palm OS Emulator, setting the
hotsync user name to that they have on the device.. hooks up
the debugger of their choice (palmdebugger, debuffer etc),
sets a breakpoint just before your comparison of N1 to N2 -
and copy down N1 (which, is the registration code)..

this topic has been discussed:

key point is everything is "crackable" - with the right amount of
effort.. what you need to do is consider what level of protection
you need - to suit your support/expectations of sales.
this topic has been discussed to death tho - you can search the
archives for a deeper discussion on this topic.. you might even
find some good flaming going on between a number of users going
into issued such as licensing et al (myself included) :P
i believe there was a discussion at the game developer conference
earlier this year that mentioned software gets 80% of its sales within
the first few months.. if you can deter them that long, you might have
a winner :)
keep in mind, palm software is a different market :) so, the % may
be higher/lower - depending on the demand/supply of competitive
products.. :)
