The Jini Community has approved the ServiceUI API, contributed by Artima Software and developed collaboratively with over 40 Jini Community members, as the first standard passed through the new Jini Community Decision Process.
Here's an excerpt from this Artima Software press release:
Originally released by Artima Software in April 2000 under the Sun Community Source License (SCSL), the ServiceUI(TM) API quickly became a de facto standard in the Jini(TM) Community, attracting thousands of downloads and appearing in several companies' Jini-technology based products. The ServiceUI API enables multiple user interfaces to be associated with a single Jini service, allowing the service to be accessed by users with varying preferences and accessibility requirements on computers and devices with varying user interface capabilities. In January 2003, Artima Software submitted version 1.1 of the API to the Jini Community for consideration as a standard. It was the first proposal to be considered under the JDP, an open process that allows both individual and commercial licensees of Jini technology to participate in the approval of Jini Community Standards. The proposal was voted on and passed in March 2003 and officially became a Jini Community standard on May 7, 2003.
I believe the Jini Community is very healthy. :-) Check out the "events" page on Jini.org - and you'll see that we not only have Community Meetings, but have also hosted Webcasts, Jini Fest! celebrations, Discovery, etc. In fact, we will be having another Jini Fest! event the week of JavaOne in San Francisco. http://www.jini.org/events/jinfest
As for the "little mail list traffic"... my guess is you're looking at the wrong aliases. The central Community alias is "firstname.lastname@example.org". The list gets at least around a few hundred emails a month. The archive is available at: http://archives.java.sun.com/jini-users.html
