Somewhat off-topic, but a great book on this subject is Michael Lewis's book
"Flash Boys".
Part of the book describes observers scratching their heads trying to figure
out why a company is laying a fiber-optic cable 800 miles in as perfectly
straight of a line as possible between Chicago and New Jersey. This reduced
the transmission time for data from 17 milliseconds to 13 milliseconds,
compared to the routes taken by the other fiber-optic lines. The margin can be
small, just as long as your trade gets there first before the other guys.
(Returning the favor to the group for the many great book recommendations I've
gotten here from Henry [Spencer])

I can imagine certain national security applications where extremely low
latency might be desirable but again, getting physically close is the solution.

I'm interested to find out where the flaw is in this thinking.
Solar sat power will be the biggest limitation to the compute/transmission
power available but over time this is likely to improve with the added
benefit that it's free to use.
