It looks like this company is trying to optimize gamers routing around the US by what they call bypassing the public internet and using their own network routes.

I have signed up to try it out during the Free beta. Hopefully I will hear from them soon so I can give it a try. I would think people's results would still be mixed depending on where they live in the US and also what ISP they use but we'll see.
