PHP streaming application

I have purchased the following third party script: [login to view URL] We need it to be installed on our server so we can give root access to do this. We also run plesk and we would like it to be uploaded to a specific domain which we have set up also. There is documentation here: [login to view URL] We would like there to be a page where there we can add multiple group chats to a single page (this is a standard feature).
