RE: CDNP naming

[Oliver Spatscheck <spatsch@research.att.com>]

I think this is partly a question of business model. If I sell a customer
a particular service (provide him with a SLA) it is my job to make
sure all of my peers fulfill the SLA not the customers. I guess your question
is are there any useful SLAs a set of CDNs can collectively support.
My answer would be yes.
