You could lay out every single security system used at Fort Knox and let people download the blueprints over the Net, and Fort Knox would be no less secure than it is today. Fort Knox's location is known to anyone who cares to look at a map.
Security through obscurity would posit that Fort Knox' location would not be generally known, and depend on that to provide protection.
Bingo. It should also be noted that even Fort Knox's vaults have metal plates on the interior bevel of the vault doors which outline the fault tolerances of the hardware. That means that even Fort Knox is not impenetrable.
So why is Fort Knox considered "secure"? Well, it's got one helluva Intrusion Detection System (IDS) for one. For another, it's got very good countermeasures to thwart an attacker. And finally, the certainty of capture and eventual prosecution (rather than any ridiculously exaggerated penalties for an attempt) is an unparalleled deterrent.
Yet for some reason, people overlook these simple realities when it comes to computer security and computer crime.

To agree with that poster's statement as you did certainly calls your decision making into question. Publishing the complete blueprints of Fort Knox's security systems will NOT make it more secure, jeez man, what are you people smoking?
