Just as a sidenote on the discussion to use nginx for reverse proxy with socket.io, the way I understand it at least, nginx 1.0.x which is stable version does not support proxying of http/1.1 connections (which is needed in order to make socket.io work with websockets). there is a workaround described on here: http://www.letseehere.com/reverse-proxy-web-sockets to make it work, or use something like this: https://github.com/nodejitsu/node-http-proxy instead, the guys at nodejitsu says this should support it.
