I would agree with Dave, your better off going with a hardware based LB and not even using clustercats. We for example run 2 seperate clusters, one set of servers for pictures and one set for CFapps. Plus you can do error trapping with most LBs' so that a 404 will get directed to another server. There is much more expandability going hardware based and all the app servers run the same load regardless.
