I believe IBM did something similar during the 96 Olympics.  My foggy
memory serves me as 

You hit the front door page.

Each mirror did a performance measurement  to you (traceroute, ping time, etc)

By the time you were 2 - 3 pages into the site, you were redirected to the
"best" mirror, based on the above.

Kind of cool, especially if IBM thought of it :)
