It's been shown in court that source code is free speech, protected by the First Amendment (cf. Bernstein v. US, Junger v. Daley). I don't want this to get to that point, but that could be a way of getting around it.

Some might argue that speech telling you how to commit a crime is not protected speech, but the Anarchist Cookbook is legal to possess as well.

Dammit Jim, I'm a hacker, not a lawyer. This is not legal advice.
