Problem with having a single machine as the balancer is that you inject a single point of failure. IMHO the balancer must support some kind of failover to a twin balancer box, or better, share load between the two balancers if they're both up. DJB's djbdns (aka "dnscache" suite) claims to do something like this with DNS but I don't believe it checks server health at the application layer, which IMHO it must if it's to be used as for fault tolerance at minimum, balancing at best.
