One thing that I don't have much of a handle on is how "real-time" this 
information has to be. If a CDN can adequately describe its network 
(capacity, regions covered, etc.) and provide a SLA that's acceptable to 
the content provider, can we get away with not carrying that kind of 
information in a protocol? And maybe if we ultimately want to make that 
information dynamic, as a simplifying matter could we tackle that as a 
follow-on?

I really don't have an opinion myself on what's feasible from a business 
standpoint, just a desire to keep things as simple as possible initially.
