How can an attack be both a DDOS and remain hidden? Please. With current virtualisation techniques, it is easy to setup a test scenario with 4 machines that demonstrate this attack. Please setup such a test setup on Xen, and provide hard data, (not 10x, not 100x) and let look at the validity and reality and quality of the setup. Either you are right and we can work on fixing SPF, or you are wrong and we can finally end this discussion. But like this, it is getting nowhere.
