Don't sure if you can trick stock NATD into doing this, but Coyote Point
Systems has a product (Equalizer) based on 2.2.8's NATD (modified of
course) that does load balancing like this.

They also have a demo (FreeQualizer) you can play with.

www.coyotepoint.com i believe.

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) |
		|--------------|
	_______________|_________________

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.
