Here is a very simplified method for selling relatively secure unlock keys to your customers. The unlock key you provide will only unlock that specific customer's download instance for a specific feature set or product.

I am a 54 year old software developer working non-stop in the field since 1979. Back then I was converting autocoder to a more high level language called assembler language (BAL) on mainframes Smile | :) Today I am a lead technical analyst for a large manufacturing company working on the .NET and IBM Java platforms. In the 29 years between then and now I have probably coded in most every language and designed software for a wide variety of applications and platforms.
