Ok so if it is web based you must have your own xmpp server. We are just trying to figure out if LCCS will be feasible for our project. Any advice on how to accomplish the ability to chat with users on aim, facebook, etc (xmpp) through LCCS. How would we go about doing this?

Is XMPP compatible with LCCS? If so, any suggestions on how to implement this? We're trying to allow chat with people on other instant message clients (aol, etc).
