What Keith wrote was that packet hijacking is bad. That doesn't mean
that one should not redirect the user to a closer copy if possible, but
that is something completely different than hijacking!
Selection of 'closest copy of service' for any protocol _have_ to be part
of the protocol itself, and not something that is solved on the IP-level.
When the user want to contatc a certain host, he should. For the web, what
is needed is a service which can help the user finding these copies so the
client can choose more intelligently what to contact, or the client should
contact a local cache or proxy, which does the job for the client.
Still, hijacking is bad...
