I remember reading something on Microsoft's webpage on how they setup
www.microsoft.com with a single IP, and had it hit several different
machines.  Maybe something like this could be done for your situation.

You could possibly fake something like:



		|--------------|
		| www.site.com |
		|  (public IP) |
		|--------------|
	_______________|_________________

	10.0.0.1	10.0.0.2	10.0.0.3


You may be able to trick natd into doing something like this.  Roundrobin
DNS on a local network only?  I know you can redirect natd to an internal
machine for a certain port... it's not hard.

There may be a certain program that does this, I cannot recall.
