From Neunet Solutions:
Add secure real-time communication to your site or intranet, for users within or outside of your firewall! NeuChat is a powerful java chat server that can run in any web browser. Users can set Preferences such as: enable Time Stamps, choose font styles/colors, and navigate through various Chat Rooms, all from the same interface. Accessing NeuChat is role based and determined by Administrators. Admins can securely manage Chat Rooms and Users by monitoring all rooms in real-time, logoff users upon demand, ban IP/Hosts from entering chat rooms, and create new rooms quickly and easily using the browser-based admin interface.
