wow, lol. Not quite enough to get worked up about. The challenge your talking about involve a UNIX protocol, something I know nothing about, but honestly most SOHO to mid level business networks arent using UNIX, mostly windows systems, server, vista and xp. Also most of the zero wipe programs out there are just that 0 wipe on a DOD alternating pattern. I'm not saying the challenge isnt real and Im not saying that you or anyone else is wrong, Im simply telling you what I have seen by example. If there was a unix prg that could be loaded and used without user interaction, and I havent used DBAN yet Im gonna give that a push this coming weekend. Then if all is correct security could be almost guaranteed on one pass, again with enough money, and time, nothing is a guarantee.
