WWW servers can issue a "redirect" to a different URL. Anybody can hack
this up with something like Apache by adding index.cgi to the index page
possibilities and then enabling .cgi as an extension to automatically run
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.

It exists right now. Several people are doing this kind of thing. It's
just not an off-the-shelf product. Yet.

Life is never perfect. ;-)
