I know the CPE will pull faulty servers our of the pool, but it does so

I've developed an embedded (Linux) load balancer solution. It's small form
factor, runs on 8MB flash minimum, no hard drive, no fan so no wories about
hard drive failure. It is LVS NAT (L4) based with configurable monitoring
service. It load balances any port you want. I've deployed it to load

You forgot to include the information about number of servers,
requests per second at peak times, reponse sizes, etc etc.
