Thank you for taking the time to go through those links, and thank you for your questions, but I'm too tired to answer them now. I'll get to them tomorrow. In the meantime, you might want to read http://news.ycombinator.com/item?id=3232368 before it gets dragged deeper into Negative Points Land by the Karma Kommandos. Feel free to ask more questions based on that comment, and I'll answer them together with the others. Goodnight.
