These are all business points. If you have enough bargaining power, you 
can get someone to agree to almost anything. If you are paranoid, that 
may even work for a while. If you seriously intend to renegotiate 
thousands of circuits involved in building global backbones every 12 
months... well, your budgets are going to start skewing in a very funny way.

Its very simple, if I have a simple network between my neighbor and me, 
I can ensure 100% diversity. 1 Wireless and 1 wired link at all times... 
as the distances increase, and the number of total nodes and paths 
increase (paths increase at something like (n-1)^2 or thereabouts), um, 
it gets exponentially more complex and more expensive to monitor.

On top of that, good/diverse/cheap right-of-ways DECREASE at probably 
close to a square root rate (especially over long distances). That is a 
fundamentally difficult problem as n gets very large.
