Shortest path to the world

[Sean Donelan]

The typical network architecture problem, what are the best (shortest 
latency, greatest bandwidth, etc) locations to connect to the every 
nation in the world?  As you increase the number of locations, how do the 
choices change?

If you only had small (2 3 5 7 11) number of locations, where would they 
be?

And what data do you have to prove the choices are best?
