our research: 

• Why it is different than all chat products on the market:   
• NO JAVA - built with html, Javascript, XML, C#, using Ajax techniques.
• NO DATABASE - no need for a database (since it is XML based). - no flashing: Based on advanced Ajax techniques the chat screen refreshes every second(this can be customized), and changes on the screen do not require a screen refresh
• NO ACTIVEX or PLUGINS, etc. - because it is not java based, the user does not need to install plugins, or to have java components on the machine. A combination of Javascript, XML and C# ASP.NET makes this possible.
• NO MEMORY STORAGE  for messages, users, rooms; everything gets stored on XML files. This feature allows several chat rooms and even chat applications to run on the same server.
• EVERYTHING ON ONE WINDOW, no popups, or additional windows needed for the chat to work.  
• pure html BANNER AND FOOTER - the banner and the footer are simple html files and can be easy customized
• EASY TO INSTALL -just unzip a .zip file on the server, create a virtual directory, create some rooms, and the chat is ready
• INTERFACE FOR ADMINISTRATORS , to create rooms, manage users, display and print reports about chat activity
• PRIVATE ROOMS -  for every user. Easy switch from one room to other, everything on the chat window
• AUTO CLEANING inactive users are removed from the chat room, even if they don't logoff. Inactive rooms are archived and  cleaned after a period of time 
• POPUP BLOCKERS OK
• ANY MAJOR BROWSER OK - IE, Netscape, Mozilla Firefox, Opera
• PRIVATE MESSAGES on the same chat window
