I agree with @Ventral:
Short answer is a resounding **NO**.
However, if you're asking how to build a framework that would prevent such jailbreaking, thats different and should be allowed.
In my opinion.
No. Only if people are reversing to illustrate how not to build security or reversing to show how good security they have. Like at blackhat 08 the stacksmashing talk showed how to get around ALSR and DEP to create an understanding of the strengths and weaknesses of the techniques.
