But, that isn't the problem that is presented. Redefining the problem away, won't solve the problem. That is what you are doing here, unless I completely misread your message. The conditions that I present are;

1) Multiple upstream providers (No single upstream provider can cover all locations).
2) Widely dispersed organization (even, multiple RIRs).
3) Cost differences, between upstreams, based on location (cost optimal link, in one locale, is sub-optimal in another locale).

USWeb/CKS, now MARCHfirst: 8000 employees, over 5 continents.
MHSC.NET: four locations in continental US, widely scattered sub-contractors.
unamed CTI development client: Hong Kong(5), AUS(6), CA/US(20), east coast/US(8), etc...

None of these are big enough to justify their own backbone operations or to buy a backbone from someone else, or there wouldn't be a problem. Paying scads of extortion money is also problematic (cheaper to simply burn the IP addresses).

I am NOT advocating tossing all of that out. I am simply bringing up a problem condition. Please, don't shoot the messenger, or otherwise get defensive (return fire is a bitch).

What I am bringing up here is that new, information-age companies, as predicted in MegaTrends over 10 years ago, are now starting to appear. They are very diffused (sparse population, over very large areas of the globe) and have connectivity needs which are both critical, yet very different from click-n-morter customers that the Big8 was built up to handle (either classful or classless). The current architecture is not handeling them very well.

The problem is currently in it's infancy, it will get much worse.
