2D Isometric Virtual Chat ( Habbo )

Looking to create a 2D virtual chat program that runs via HTML 5, or via iOS app. Great example of this would be Habbo Hotel, or Club Penguin. However, we are not looking to create it with a slew of options at first. A generic version that is up-gradable as we grow would be great. Must Be Able To Do The Following - iOS or HTML 5 - Users select a character (including gender) - Users can change hair, face, race, shirt, pants and shoes - Users can create their own rooms and decorate it with furniture - Users can chat to each other in rooms - Users can visit other user rooms or visit each other in lobby. - Must be a framework we can build on later to add things such as PMs, Badges, Achievements, point system, user to user trading etc. - Admin accounts to block, add, remove users. - We have a wordpress ran site in development and would be nice if user registration / login details were handled through wordpress's database. Please checkout [login to view URL] to see what we are looking to accomplish. However, we do not need all the bells and whistles at this time. We would like to be able to grow it slowly adding features as we go and our user base expands. Any other thoughts, suggestions or maybe you know of a pre-existing framework is welcome. This will be an ongoing project where you or your team will be supplied with projects to extend the functionality frequently. Thanks!
