But do the commonly-used operating systems support adding hundreds or
thousands of addresses to an interface, and what would the performance
implications be?

Remember that IP addresses are 128bits, while hostnames (the ones for
the "Host:" header in the HTTP query) are well, quite a bit longer than
that on average.

If thus something like this would become common-place, there definitely
will be quite some people who will be paying some attention on
optimizing Apache.

But yes, the network stack itself is a different question, then again,
you can just route a /64 into the loopback device and let your apache
listen there... (which also allows you to do easy-failover as you can
move that complete /64 to a different box ;)
