CDN List - Affordable and Effective CDN Websites

I use MaxMind for the data table under the waterfalls as well and it's usually pretty good but sometimes it is WAY off (like all Google POP's claim to be from California because that is where their IP space is assigned). Maybe less of an issue for end-user connections but it's probably not worth the lookup time.

One of the things I wanted to add to the Linux TCP layer was a way to get the current RTT estimate which might give you a guess as to how close the user is to your server but that would require that the connections are terminated at the server itself and that the information get exposed up the stack.
