Are there DNS servers that count the number of hops between the end user and the possible webservers, and then reply back with an address that is closest? Or maybe figure out the fastest? Or are there web servers (or a CGI or Apache module) that count the number of hops (or the amount of time) between it and the client -- and then either send a HTTP redirect or modify the HTML image or href links to point to a closer server?
