Prototyping main website mirror selection

Hi all,
    in the past few days I have toyed with a javascript-based
client-driven mechanism to help drive website users to their closest
mirror; I'm experimenting with it as one of a few possible schemes to
implement our own squid-based content delivery network.

So far I have a functional prototype of an user-initiated
client-driven javascript selector; I'd like to have feedback from you
on it.
I encourage those willing to help to visit
http://eu.squid-cache.org/findmirror.html and report their thoughts.

Thanks!
