This is a upcoming project, yet to be released by Sun folks. MPK20 is a 3D virtual environment designed to enhance business collaboration
The MPK20 software is built on top of the Project Darkstar server infrastructure. Darkstar, a platform designed for massively multiplayer games, provides MPK20 with a scalable and secure multi-user infrastructure well-suited for enterprise-grade applications.
On any given day, over 50% of Sun's workforce is remote. MPK20 is a virtual 3D environment in which employees can accomplish their real work, share documents, and meet with colleagues using natural voice communication.
Just like on Sun's physical Menlo Park campus, known as "MPK," inhabitants of the virtual MPK20 office building can work together in planned meetings. Unlike the physical campus, however, in MPK20, the community can be built and maintained without the constraints of physical location.
