This is a terribly interesting idea. hehe... I *really* like this one.

Of course, this begs several questions:
	(1) What are the legal rammifications of such activity? If I were
	    to write a trojan cracking tool, would I be able to be accused
	    of criminal activity, even though I'm really a good guy?
	(2) A number of us no doubt lurk in bad guy hangouts already, but
	    how would we be able to propogate trojan cracking tools in the
	    intruder community? It stands to reason that someone who knows
	    what he's doing will examine the code at some point, understand
	    what is happening, and spread the word... Maybe binary-only
	    distribution?
	(3) Is anyone really interested in doing such a thing (assuming
	    that such a thing won't get the author jailed)?
	(4) What does this have to do with firewalls? Nothing directly, so
	    please follow up to me privately on the subject...
