@Jeff, looks like most of your commenters have more information on this one than you, this time. As one said, I too am surprised you fell into this naive trap, designed to grab the imagination of the non-techies. One VERY important element, absolutely inherent and critical to proper functioning of well-performing networks, is Quality of Service (QoS). Net Neutrality effectively makes QoS illegal. And that's really the only thing it can accomplish. If an ISP really wanted to harm your bandwidth, it would be trivial to do so, and in such a way that it would be impossible to prove it. This is just like it is impossible to optimize metrics on programmers... Hmm, now you got me thinking, could it be that it's secretly AT&T that's behind the Net Neutrality? That's one way to kill all the VOIP traffic (which depends on QoS, and would be practically impossible - or at least unusable - without it)... And thus get back control of the Bell monopoly... Really, that's the only thing that makes any sort of sense (except maybe a soviet plot to destroy our infrastructure). Please, Jeff, look into this again, and come back with a retraction / correction.

Kind of nitpicking here, but I recently discovered (http://security.stackexchange.com/q/379/33#440) that Rainbow Tables are NOT just large lists of hashes of all possible passwords. It would actually be more correct to call them "Hash Chains", rather than the "Hash Tables" we are all familiar with, and most of associate with Rainbow Tables. Yes, it seems even some of the tools call it by its wrong name... User @Crunge on SE really opened my eyes to this one, even though I *knew* what Rainbow tables were - or thought I did, as it turns out I didn't. And I am also one of those considered by others to be an "expert" (in security, though not specifically cryptography). Seriously, it's an awesome post, one of the best answers I've seen on SE - go check it out: http://security.stackexchange.com/q/379/33#440
