I am looking to hire a developer to create an app based on an idea I have and in preparation have hit a bit of a roadblock.
For my app, part of the functionality is meant to have a chat-room like feature where by a large number of users can be have live converstations.
Now I have seen this implemented on a 1-to-1 basis and with small groups e.g. WhatsApp and Skype, however I cannot see a app on either iOS, Android or WP7 that allows for much larger 20-30 person chats. The application should not be limited to people that you keep on a contacts list, the application would allow free chat between anyone with the application but filtered by different chat rooms.
Is there a technical limitation with mobile development that would make this difficult/impossible or am I just not looking hard enough and this functionality does already exist?
A good test of my question would be, could you create a replicate of the chat.stackoverflow.com pages in a mobile app? I am unfamiliar with mobile app development myself but would have anticipated that something like a chat-room app would already exist.
Thanks, James
it's possible and very easy if you are going to send messages through web server. consider in room there are 3 persons,and you have 3 ids,for example 1,2,3 . User's room id can be for example 2_3,if his/her id is 1 .and when sends message,he/she also should send 2_3. Your application can do http request for example with 1 minute timeout for receiving message(you can use comet technology).
