Re: Adjusting CPAN::Mirrors to make it more useful

I think I may have implemented what you're looking for several years
ago for JSAN, which has a client that auto-detected appropriate
mirrors in a few seconds each time it starts.

http://search.cpan.org/~adamk/Mirror-URI-0.90/lib/Mirror/YAML.pm

Or at least, something similar to it.

It autodetects mirrors, can validate them for both speed and
staleness, and doesn't give a crap about where they or you are
physically in the world.

It auto-updates to new master servers, and is resistant to mirror/repo
hijacking, and it can (with a tweak to support an async library) do it
in parallel.
