IMTU I call them HighPoints, and most civilized worlds have at least one of them (e.g. one for passenger traffic, one for freight, one military, and so on). They are usually run by the system governments. The freight and military ones are usually off in deep orbit somewhere. This makes them easy to access for bulk carriers and also keeps the said bulk carriers away from populated spaces. On super-hi-tech systems there might be a beanstalk physically connecting the planet and the HighPoint(s). > that's not covering the need for agriculture ... I've always liked the idea of huge orbital farms in the style of "Silent Running". Stick some (big!) solar arrays onto them and grow all the vegetables you want. Jonathan
