As part of the KamiJS project, we have started work on integrating OpenLaszlo clients with server-side JavaScript based web sockets (similar to what people do with Node.js) using RingoJS. Check the wiki page http://wiki.kamijs.com/JavaScript-Sockets and the code repository https://github.com/kamiJS/websocket-server if you are interested.
We are still looking for contributors as well, please ping me if you are interested in working with us. - Raju
