You miss the point; what they have done is decouple the requirement
for correlation to a geographical location in optimizing content
delivery; the only thing they seem to care about is logical
topographical location.
Well, "they" probably look at things like throughput and packloss, as well as logical topology / RTT.

But what do I know? :)


As for the 'pretty hard work' part; they seem to be making money off
it; how's your gig going?
Not sure that's a fair comparison, since I didn't think William is doing this for money. (William, can you confirm?) Someone offering "less" service, but for "less" (or no) money seems perfectly reasonable. In fact, it's downright nice.

But doubt it would be as accurate. (Which is not a slight against William.)
