This chatroom application can actually maintain the same instance over MULTIPLE websites/servers.  For example: You can host this chat application on chat1.com and quite seperately on chat2.com (two completely different websites) and users in EITHER chatroom application on either website can talk with eachother.  That means that you can integrate the exact same chatting instances for all users on multiple web applications!  This means that people on chat1.com can talk with people on chat2.com!

Try opening two browser windows and running (Product Demo's -> Extreme Chat) and then in a seperate window run (Product Demo's -> Extreme Chat (Clone)).

This is used to show that the very same instance of this chatroom application can run on multiple pages/websites/servers.  You can actually have the exact same chatroom application instance running on 2 (or more) completely different websites/servers and people on ANY of your sites can communicate with eachother as if they were in the same "Chat Instance".
