I'm the inventor of Fling. Fling is similar to ZKS, but with subtle difference: the route is prebuilt *from the recipient, back to themself*. The sender picks up this prebuilt route frome someplace or via some search system, and uses it to guide a data packet. The data packet can be their own return address, allowing bidirectional communication to be set up. good results: - the anonymity hides the IPs of both parties, unlike ZKS - there is no need for a (economically and strategically vulnerable) company to control things, it can be totally peer-to-peer bad result: - you can't anymore use it to route packets to normal IPs (since IPs are hidden), except maybe via some third party proxy service. To get the full security benefit, data packets must stay inside the Fling system all the way. The current status of Fling is: designed, but not built. I'm in progress of building the underlying encrypted packet relay system ATM, once that's done I'll move to building Fling on top of it.
