Exactly! The problem is how to decide which CDN is 'better'. For example is
Digital Island or Akamai better for my desktop computer (now or in 1 hour) You
need some more details about the internals of the CDN to make this
decision. The question is which information is required, which part of the
system manages that information and how should it be transmitted. I guess we
should agree on those high level aspects first ... .
