yeah--I realize Harriman is a Heinlein fictional company. I couldn't think of any Clarke fictional companies. On the other hand, I guess I read "commercialization of space" into "space tourism", and space tourism can be a government activity. Still, I suspect space tourism will ultimately be commercial more than government, and THAT would be what drives future space expeditions.
