Is it not possible to require that each of your suppliers provide  
over a specified path ?  I'm planning a build-out that will require a  
diverse path between two points, and one supplier has named two  
routes, and promised that they wont change for the duration of the  
contract.  Perhaps I am naive, but a promise should be a promise.

Also instead of buying path A from supplier X and path B from  
supplier Y, it might be worth buying paths A and B from supplier X  
and a spare path B from supplier Y too.  Supplier X must know they  
only get dollar N because they can provide both paths.. and in  
addition diversity has to matter more than money because you are in  
effect paying for one path twice.
