WWW servers can issue a "redirect" to a different URL. Anybody can hack

a CGI script which could issue the redirect in the HTTP headers instead of
emitting an HTML document. The CGI script would only need to be a simple
table lookup similar to what a Cisco's SSP does. Of course their needs to
be something more intelligent (like BGP to continue the analogy) that
builds and maintains the lookup table based on some sort of heuristics.

Isn't IBM doing some sort of fancy load redistribution for the WWW 
servers its running for the 1996 Summer Olympics?  I seem to recall they 
were determining the "closest" server via a technique called "ping 
triangulation", whatever that is.
