Email & Instant Messenger Sever / Client

Hello, Briefly what I want: Part 1: ------------------------ Phase 1. IM Sever Phase 2. IM Client Part 2: ------------------------ Phase 1. Email Server Phase 2. Email User WebMail Description: I need a professional, modern and high featured Instant Messenger be written in C++ or C#. It should be Cross Platform (Windows, Linux, MAC), so you can use Qt or Mono or etc. to make it possible. The job should be done with highest technology and new methods in programming and a good architecture. It should be stable, fast, secure and easy to improve (develop). The client should have a pretty design using WPF or other techniques. I want something like "Microsoft Lync" and I want all it's features including other features which I want on this project: 1. Text Chat 2. Voice Chat 3. Video Chat 4. VoIP 5. Desktop Sharing (Presents or Remote Control) 6. Browser Sharing (A simple browser which both sides see and use together) 7. Whiteboard Sharing (Something like Paint which both sides can see and use together) 8. Chatrooms ... ... ... The server should be run on Linux OS (I thinks windows is not stable enough and need more resources and has much more costs, other side is the Security that you know about that), I need some private web panel to manage and see analysis on it. Here you should use MVC architecture and make sure about security. Also here I need a pretty design using "CSS 2 & 3", "jQuery, MooTools, Sencha or etc." and "xHTML4 or HTML5" and it's good to be work using PHP with CakePHP framework. The server software should be very stable and secure and can handle lots of traffics on it, I need a high performance one. Also I need some APIs to get/send data from my websites (integrate theme). The server system should be able to connect with mirrors and use Cloud-Computing in case of expanding the network. Email Sever and Client are almost the same. I need the best work and design. All data will store on a Central Database Server. So all systems can use some APIs to connect with this server and manage data. It should be relaible and safe and very fast computing. So use a database engine able to handle lots of queries at the time. Designing of database structure should be engineered and right. ------------ Attend that I myself am a Programmer and know about all these languages and techniques, So I know what I want and what should them be, So please bid when your team are ready to do whole it well.
