From the OP question I understood he is not sure whether somebody else ("one") can read out his code from the ADuC or is it protected well enough. I think it is fair to bring up possible security flaws. While we agreed on another thread that absolute security does not exist, there is no point investing in a product that can be copied too easily.

And, there is nothing gained by security through obscurity - if there IS an obvious security hole which is trivial=cheap to exploit, from almost every aspect it is better to bring it to public.

An another view: what I wrote is so evident that there is no need to disguise it.

Still I have not tried so I cannot say if it would work or not and how would the security bits interact with something like this.
