PHP throws an error "Only variables should be passed by reference" at line 317 (ownet.php).
At least stream_select() functions in the scripts should be corrected (it accepts only variables and two integers).
I got it working somehow by changing "stream_select($read = NULL, $write , $except = NULL, 0,1000)" to "stream_select($read, $write , $except, 0,1000)"
