The only problem with Activelock is that it is open source, making it easier
to crack.

To automate unique software, how about using IncrementalBuild()? I could
work like this:

A user registers on my site. ASP scripts add a custom generated key into
the application source code. These scripts execute IncrementalBuild() to
recompile, which only recompiles the one method that has changed. I provide
the user with an email of the custom code and link to download the app. He
puts in the code, which unlocks the app. The code is encypted and written
to a text file. Each time the app starts, it checks the text file against
the hard coded code.

Any problems with the above?

Thanks,
Brett
