Somewhere 'security by obscurity' actually helps: power grids

As it turns out, the old 'security by obscurity' approach does actually work in some place, like electric power grids.  This Wired article talks about what it would really take to manipulate electricity in the United States.  While its not insurmountable to achieve domination and control over the power distribution system, it takes a whole lot of knowledge that your'e not going to gain through casual reading at home.  This was a good read.
