One optimization that occurs to me is the use of the Host header to
distinguish requests for different domain names but use a single IP
address. This should reduce the size of the address tables and
generally scale better in other ways (no need to manage IP-space
allocation, ability to host on the Internet without a huge IP-space,
etc).

Does anyone know of a way to convince HTTP clients doing DNS lookups
to send *all* subdomains to a single host and terminate name
resolution for a domain? If we could figure that out, you wouldn't
even need to modify the DNS...
