implementation of Lotus Sametime Community Client protocol
Meanwhile library provides the basic Lotus Sametime session functionality along with the core services; Presence Awareness, Instant Messaging, Multi-user Conferencing, Preferences Storage, Identity Resolution, and File Transfer. This extensible client interface allows additional services to be added to a session at runtime, allowing for simple integration of future service handlers such as the user directory and whiteboard and screen-sharing.
