I never used that feature, but, why not use the "built-in" IPC channel given by fork?
http://nodejs.org/api/child_process.html#child_process_child_process_fork_modulepath_args_options In addition to having all the methods in a normal ChildProcess instance, the returned object has a communication channel built-in. See child.send(message, [sendHandle])for details. Then http://nodejs.org/api/child_process.html#child_process_child_send_message_sendhandle with examples, child.send, child.on, at parent side, and process.send, process.on at child side I guess there are more info at: http://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options 1. 'ipc' - Create an IPC channel for passing messages/file descriptors between parent and child. A ChildProcess may have at most *one* IPC stdio file descriptor. Setting this option enables the ChildProcess.send() method. If the child writes JSON messages to this file descriptor, then this will trigger ChildProcess.on('message'). If the child is a Node.js program, then the presence of an IPC channel will enable process.send() and process.on('message').
