sockets - communication between chrome extension and desktop app?

Question

I am developing a chrome extension which needs to communicate with a desktop app (non-web). The app uses winsocks so ideally the chrome extension should use some raw socket API for input/output. The socket API seems still experimental, though. What are my other options? In a similar Firefox extension, I used nsISocketTransportService, nsIScriptableInputStream and nsIInputStreamPump to achieve the purpose. I am looking for some equivalent in chrome. Thanks.
