Installation Code for Limited Time Demo

[Steverino]

I've created a limited time demo base on the "Bomb" sample file. But now I'd like to create a scheme so that users who pay for the database can enter an installation code to disable the time bomb.

I've created a calculation field called "Unlock Code Formula" with the following formula: "XC346B8SV" & Right(UserLastName, 1) & Right(UserFirstName, 1) & Right(NumToText(Unlock Date), 1) & Left(NumToText(Unlock Date), 2). Then, I'll give my customers an installation code that corresponds to their user name and the date that they unlock the demo. When the installation code = the unlock code formula, the time bomb will not be activated.

Here's the problem -- what's to stop people from simply copying the already-installed set of files (as long as they don't change the user name)? Is there another way to prevent people from sharing the files? I'm using Developer to create a runtime solution.
