    Oops. Most ISPs want to have
    www.isp.net
    www.customer1.com
    www.customer2.com
    ....
    www.customerN.com
    on a single host, because their customers want the illusion of their
    own web server.

    I'm against this idea categorically.

Good point about the current naming schemes.  But then what does it
mean if a client sends:

	Host: www

To me, this is an error, and the server can report it as such.
What else could it possibly do?

So perhaps I would modify
> 	(3) server administrators SHOULD NOT configure servers

to be
	(3) servers MUST return an error [to be specified] if
	a client sends a semantically ambiguous prefix in a
	Host: header.
