Flying cities

I've got a dream, a plan to send mankind into space. This won't be the last time I mention it here. It's very simple actually, I have an aerodynamic method of building cities in the sky and without too much of a leap of technology they become self-sustaining cities in space. It's not so much the technology that concerns me as the societal development that is required to live peaceably and which I am hoping is definitively assisted along by properly designing the city to promote co-operation amongst the residents.
