Sun provides assistance by having one or more experts on the Jini technology assist the working group with any Jini technology-specific questions they might have. There are three basic models under which community members can choose to run Jini development projects within the community. You may Share the project with all members, using freely available Web space on the jini.org site. The project is jointly developed with other interested members of the Jini development community as a public project. Code is protected by the SCSL and site login, but developed interfaces are returned to the community.
Vendors can build their own commercial implementations if they so choose.
Develop the project without community input, but publish the design and code after completion for others to use. Sometimes referred to as cut and run, this model allows a community member to contribute something that he developed on his own but believes might be more generally applicable. The developer has the option to contribute only the design and interfaces without implementation. Build a Jini-based project completely internal to one's own organization, not sharing the design or code with the community. Sometimes called the microcosm approach.
