We require a fairly simple .Net Messaging application to be written, in C# or VB.Net using .Net Remoting. A kind of basic MSN Messenger, but for business purposes (with a more professional interface and without relying on Windows Live authentication). Please see the attached specification. This should use Windows authentication, with a .Net Remoting server. It needs to be designed so that it is expandable in the future to include video, audio and whiteboard functionality (so there should be generic data transfer built in.) It will also need enhancing to work with Cisco Call Manager (and integrate with the IP phone system) - we can make these changes, but the application will need hooks to facilitate this - please implement stub functions for us to complete. Unfortunately the budget on this is tight, so this may suit a hobby programmer... ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). * * *This broadcast message was sent to all bidders on Thursday Oct 11, 2007 8:04:01 AM: Hi - the specification attachment should now be attached. Thanks, Ben. * * *This broadcast message was sent to all bidders on Saturday Oct 13, 2007 5:26:42 PM: Please note that this needs to be a server-based system. That is, clients talk only to a server, and when a client sends a message to another client, it sends it to the server which sends it on to the other client. It should be possible to install both client and server on the same machine (for a standalone installation), or on different machines (so the firewall for the server can be configured appropriately). Each client belongs to one server, and for communication over an Intranet there would typically just be one server. But for communication across the Internet, the client would connect to its' server, which would connect to the other server over the Internet and then on to the client. In this way, we dont have to worry about client to client peer to peer connection and firewall issues. The client to server and server to server connections will be via .Net Remoting, using TCP and/or SOAP channels. The server will need a SQLExpress database to store configuration / address details and pending/undelivered messages in. Additionally, a working prototpe will be required about halfway through the development for client feedback. This is critical as I won't have much time to talk you through a detailed specification at the start - I need to know that you understand the problem and technologies, and we need to start with a basic working prototype (of the architecture described) and then evolve it to fully satisfy our clients requirements. Please confirm that you are happy with this architecture and approach, and retract any existing bid if you are not happy. By the end of this week I'll narrow it down to 2 or 3 potential bidders and ask you to summarise your approach. Thanks, Ben. ## Platform Needs to run on Windows 2000, XP and Vista (all editions)
