	Sure, you can use static routes as well[1].

	For those that are interested you can take a look
at http://www.submarinecablemap.com/ to get an idea of what path
might be feasible.  I will say that telecom costs tend to be
related to political stability, so when computing shortest
path cost often comes into play.

	Also, What I'm often reminding people is low-latency isn't
always the right solution, because loss is more important.  I am
less concerned about another 25-100ms if there is little jitter
and zero loss.
