Developing a MSN Chat-type application on Facebook.

Looking forward to develop a chatroom(s) based application on Facebook. If you're aware, MSN Chat used to be an IRC-based Chatroom platform, with MSN + user-created rooms. I'm looking forward to replicate the same experience on Facebook, with the following features - 1) IRC Based rooms (hosted on our own servers) and managed by us. 2) Flash OR Java based client which helps user access the chatroom. 3) Real-time chats, emoticons, actions and moderation in room(s). 4) User-created rooms to have their own moderators (3 level of moderators - gold / silver / bronze) and ability to manage rooms (mute user, kick user, re/de-moderate users, deleting rooms etc.). 5) Zones for every country or continent - App-based rooms to be featured on top and user-created ones below them, with about 20-30 rooms on each page. 6) Ability to connect to the chat-rooms using IRC Clients (and obviously run incredible trivia / quit / vote scripts). 7) Ability to see a user' FB profile from chat (they can then add them as friends). 8) Unlock achievements and ranks based on user-vote, time spent, words spoken etc (optional at this stage). 9) Built-in filters to minimize abuses (in the client). 10) Create "Featured Rooms" by users, for some credits which can be earnt or bought. 11) Buy special emoticons, personas, fonts, colors etc via virtual credits / currencies. (good way to monetize). 12) Display Ads above the app and below it. 13) Ability to ban a user and / or IP from accessing the game. 14) Abuse report system (optional). 15) Full FB Integration and App. 16) Possibly creating Tabs, which can be added to other apps (like their own chat-rooms). 17) 30 days of support (to iron out bugs, glitches, if any). Deadline: 30 days.
