low-latency high-bandwidth OS bypass user-level messaging for commodity(linux) clusters with commodityNICs(<$200), HELP! (GAMMA/EMP/M-VIA/etc.)

One can assume the streaming (-s) option, though.
The latency is pretty good. Typically only achieved
when running in direct mode over GigEth without
the stack.
