The RedHat Load balancing clustering tool (piranha) might looks a bit complex, but in reality, it's just a fancy wrapper around ipvsadm which is the user-space tool for the kernel traffic director. I havent played with Nth module, but ipvsadm is probably more tested.
So, we don't have a hardware balancer ? are we searching for a software balancing solution ?

Honestly I didn't.  I thought about using some of the RH clustering
suite but it will add a bit more overhead then we want for our current
environment.  Do you have a link to some good documentation for iptables
based load balancing?
