If they're all iPhones/iPod Touches, you only need to buy the game once. I don't even know if there's a restriction on the number of mobile devices you can put the games on. (You are, however, restricted to 5 computers to sync to them on the same iTunes account.) We have 3 such mobile devices in our family that we do this with.

Paper ballots, but prefabricated results. (With many jurisdictions turning out many more votes than voters, and in many cases preliminary reports coming out almost the opposite of the final reports.)

I wonder if this is becoming an industry.

If you read the article, this was one of the author's points: He had gone into this thinking like a consumer, and realized that thinking like a consumer isn't enough when you're talking about high availability/high throughput systems.

The article may be worthless to you because you may have an admin background, but I know of a lot of so called "admins" who don't understand some of these basics, as well as a lot of developer types.
