The application I was thinking about was software to decode car radios, the actual object code of the radio on certain models is uploaded into the radio, so its not something you'd want to write yourself, decapping and other fiddling in this case might be worth the effort, well let me re-phrase that, certain individuals would be prepared to invest time and effort in means to copy the firmware, certainly not something I'm into.
Theres also those that want to say look what I can do.
I found the subject interesting as there have been times in the past where I have wanted to protect my intellectual property.
