Idea: you mentioned starting a city in the past. This summer when I was driving my wife and her parents around Oregon[1], we happened to drive through the ex-Rajneeshpuram[2]. If you could get a decent internet connection happening, that would be a great place to build a hackerville - it's beautiful country, has a lot of facilities already there, and hey, maybe you can start your own collection of Rolls Royces. I don't want to have to dress up in orange though.
