Connecting DMC websockets to a socket.io server

Hi,  Has anyone successfully connected a corona app to a server running node.js/socket.io ?  I tried using DMC websockets ( it’s part of the awesome corona classes/utilities from David McCuskey), however for some reason, the app just freezes. The port that I am using is open in the firewall.  The objective is to include a chat functionality in the app.  Appreciate if anyone can provide any  tips for debugging this – Thanks.

DMC Websocket are available here :  http://docs.davidmccuskey.com/display/docs/dmc_websockets.lua

Server :  ubuntu 12.04 lts.  Node.js - v0.10.31.  Socket.io - 1.0.6
