I did not see much info about this, so I thought it might be interesting to share it: the 31st of May will be the CommunityOne UnConference held in Hall A at the Moscone (Wikipedia, GeoHack), the Sunday before JavaOne, May 31st. Those different products will be covered: GlassFish Portfolio umbrella (Server, WebSpace Server, ESB, Web Stack, Hudson, Communications Server, Mobility Platform) as well as the Identity projects (OpenSSO, OpenDS, IdMgr, RoleMgr)...
Few interesting link to get more info:
