Background: I'm one of the developers for SuperTCP (http://www.supertcp.com), a simple driver-based TCP accelerator. We've found it performs pretty well on AWS so we're thinking about releasing a base AMI that has NGINX + SuperTCP so you can get TCP-accelerated load balancing without buying an F5 or something like it.
Thoughts? Would that be useful? How about experience with other TCP accelerators?
Here is a blog post with more information about how we "accelerate" TCP: http://supertcp.com/the-fundamentals-of-a-killer-reliable-transport-protocol-for-the-internet/
farawayea's comment is just not worth considering, not all software must be open source to provide value or have people use it. If it works, it does what you team says it does and there is a market for it people will pay for it, regardless of whether it is open or closed.
A question for you, I didn't see anything on your site (maybe because I skimmed it) but does using SuperTCP increase security at all, do nothing for security or ?
