Pen - A "Simple" TCP Protocol Load Balancer

Pen

"This is Pen, a load balancer for "simple" tcp based protocols such as http or smtp. It allows several servers to appear as one to the outside and automatically detects servers that are down and distributes clients among the available servers. This gives high availability and scalable performance."

While there are many open-source "load balancers", this one seems intriguing because it looks very light-weight.
