Behold the Gumdrop! (RTC Presence Toolkit announced)
Microsoft has now formally announced the "RTC Presence Toolkit" at the Worldwide Partner Conference 2005. If you were at my presentation at the Office Developer Conference UK last month, you saw a demo of the beta version - which is variously referred to as the "Persona" control and the 'Gumdrop' control due to the new icons used by Office Communicator :-)
The toolkit will make it way easier for developers to add presence, communications and contextual collaboration to their own applications. Gumdrops everywhere! The toolkit should hopefully be released in July - keep watching for the release to msdn!
