> What is a little difficult to grasp is what patented, arithmetical equations are being used and why they work. Which is why TCP/IP is going to be around for a long time yet, and very unlikely to be replace by a closed, proprietary alternative. The TCP/IP spec is open to all - if you want to build a network or device that talks TCP/IP there's the specification, have at it. The open nature of internet and web protocols helped make the modern internet possible. We should not be so quick to shut the door on such a rich and productive legacy. (Or, at least, refrain from writing hyperbolic headlines). That being said - a company selling an alternate, high-performance networking protocol could have a strong market. ISP routing over the last mile, educational/research or any other institution that operates a WAN may be a good customer.
