As you may know the available version of Messenger at http://www.jivesoftware.org[/url] implements 90% of the MUC specification. Our goal is to have a full implementation by the time the 2.0 release is out.
So far I added the following new functionalities:
Ability to define sysadmins of the MUC service: A sysadmin is allowed to enter any room and behave like an owner of the room.
Ability to register with a room: When you register with a room you become a member of it and if desired you can reserve a room nickname.
Ability to discover reserved room nickname: Before joining a room a user may want to discover if he has a reserved nickname.
Persistent rooms: This feature is currently under development. Persistent rooms will be saved to a database. Currently Messenger supports: Oracle, MySQL, DB2, PostgeSQL, SQLServer 2000, Hsqldb and Mckoi.
