I think it the issue is not necessarily searching but the selection
of the best servers.

Selection by the client side is the issue to be solved by policy routing.
That is, if a policy is rich enough to select the best route to some server,
it is also good enough to select the server with the best route.

But, if we urgently need it some static scheme should be developed.

Selection by the servers' side was once addressed in DNS load balancing
sub WG and, I think, a solution was presented.
