Latency is...
bash-3.2$ ./socat TCP-LISTEN:5001 PIPE & exec
99<>/dev/tcp/127.0.0.1/5001 ; time for (( a=0; a<1000; a++ )); do echo
$a >&99; read <&99; done; exec 99>&-
[1] 4492

real    0m1.959s
user    0m0.062s
sys     0m0.172s
bash-3.2$
[1]+  Done                    ./socat TCP-LISTEN:5001 PIPE

...about 2ms round-trip. How is this a problem?
