I don't see how it would work doing the load balancing at the web server level. At that point, the request is already at the web server (which may be the wrong server for the intended content).
And without a load balancer between the user and the web servers, how are you determining which web server is to be used to process the request in the first place?
Pound looks like it may fit the bill though. It was one I put on my short list to look at in more detail.
