How is active-active possible

it's Horms experimental code called Saru. He explained it at OLS one year you didn't come.

http://www.ultramonkey.org/papers/active_active/active_active.shtml

Downloaded and printed, will read this weekend. Although, if Horms engineers something it's most likely flying anyway. So I just have to understand how he cheated the TCP stack this time :). I see some netfilter related stuff in it and I wonder if (from what I've seen) his approach works for 2.6.x kernels with proper TCP state tracking, TSO and USO? In 2.4.x where netfilter is mostly broken with regard to TCP state tracking, such quirks might be possible.
