Depends if you need folks there to run the Nano-workers, and folks to support 
those folks.  All industry has the bulk of the real work done by machines.  
The machines are directed by workers.  The workers derected by designers and 
managers.  They work for investors and customers.

Nano-tech as a technology is as major a step as steam or cybernetics were.  
As to the third world, they follow us - and obviously only their technically 
advanced representatives will get involved in space or cutting edge anything.

You forget the asteroids and old comet cores in space itself oil, high purity 
minerals, zero G, high power solar are all in abundance.  You have to build 
your own land, but their are plenty of minerals to do it with.
