Just a quick note in clarification, I am less interested in intelligently directing the traffic to the closest or most optimal server farm that I am in purely ensuring that the traffic can be balance between sites that sit within different AS's.
How do you propose to do this? It is a non trivial solution - if you don't believe me, go ask someone trying to do it (eg Akami).
People forget the magic tenant things are built on here - "The less the control you have on a network, the harder you have to work to deliver a given quality of service", where quality of service is something other than 'terrible' .
Naturally, if it was a trivial issue, we wouldn't be debating it here. I don't necessary propose one optimal way over another. I have simple made the statement that a DNS oriented approach can be feasible in many situations. As far as magic goes, I'd like to meet the group that runs the entire Internet because that is the network I'm concerned about. QoS at this point is not the issue at hand in its normal sense.
