There is not "no way to do any of this." People do it all the time. =
They do it using anycast, which requires a certain amount of network =
build, or they do it using source-address databases, which have a =
certain amount of ridiculous FAIL. Are you actually asking why there's =
no way to do it perfectly at no cost?
