So far nothing I've seen would allow a single URL to be used to access the "nearest" server. Until something like that exists (i.e. the end users don't need to know a thing about network topology) it seems pointless to align WWW servers with the topology. Your suggested use of redirects just complicates things -- consider how the URLs would end up looking in a search engine.
You first have to get a decent metric for "nearest" down first, and then be able to measure and use it. Something basic like AS path lengths doesn't work, so you'll probably end up having to use something like history of RTTs. Not an easy problem to solve, to put it mildly. -dorian - - - - - - - - - - - - - - - - -
