In some embodiments, the disclosed systems and methods provide a client-server infrastructure capable of supporting a variety of asynchronous and synchronous collaboration activities in a so-called collaboration place. Some of these activities include chatting, viewing and/or editing one or more data files, and sharing one or more applications, data files, and/or displays. The client-server infrastructure supports seamless navigation between the supported asynchronous and synchronous activities in the collaboration place. Additionally, the client-server architecture supports data persistence, so that data files associated with the collaboration place can be stored for subsequent access.
