Right. But your situation is not the one being looked at, as you don't have
geograpically distributed web servers. I believe for that situation 3DNS,
et. al., can work. Once the client's DNS request has worked its way over to
the primary DNS for the distributed web-servers, 3DNS has each of the other
3DNS boxes (located adjacent to the other distributed servers) ping the
*clients* primary DNS. 3DNS then returns the URL for the web-server whose
3DNS machine is 'closest' (fewest hops) to the clients DNS machine. Thus,
for example, clients in Asia can get to a server in Asia.
I think that's the gist of it, if not the specifics...
