Advanced Random Chat System

I need advanced random chat system. Now I have about 1000 users online during the weekend, so chat system need to resist much load. Multi-proccess system is maybe only good solution. Chat system need to log every chats, user connections, times and IP-address (mysql-database?). My site now: [login to view URL] (finnish) I need new system because now system crashing It have not API and code is very ugly. Requirements: - User counters for every chat. - API and documentation for it - you can not get same user next time, but after it user can. - Clear code and comments least in frontend code. - Mobile-compatible is good, but not mandatory. (I do mobile apps with chatsystem API) - Sound and title notification new message if window is not open. User can mute sound. (Desktop Notifications also maybe?) - If user try close window accidentally, he can return chat. confirm-box - If user lost connection he can go back. Other user get information if other user connection lost. - If server crash, it start again and don't lose chats. - Chat frontend language is finnish, but I translate. Editable texts. - Ad-place and "Copy chat"-button after chat. - Cool layout is not important, because I style it. You need name objects well. - Smiley support - Automatic link or other normal stuff in chat. - User dont see own message server delay. - Random writing..-text, if Random writing. - IE8 support - Chat log-page (not mandatory) 3 different chat types: one-on-one chat: - like Omegle, normal random chat group-chat: - 2-6 random users (editable config value) - Nick like: Random(33) and random color (server give those) - spam protection by server (editable config values) - if room have place, new user can join. - If room is full, server create new room if over 3 wait free place. If no body room, room removed. sex chat: -You can choose your sex, chatter sex and age (18) No PHP+JS+MYSQL-systems! You can do it example with node.js, but NO SOCKET:IO! XHR-polling or Json-polling could work well. When you bid, tell code language and other blocks for chat.
