I would like to have the following features in Jabber chatrooms:

- system notification when user says any one of a list of trigger words (i.e. nicknames)
- ability to 'silence' selected people, so that their messages do not trigger sounds
- ability to mark people as 'special', so that whatever they say a system notification will be created (regardless of whether or not they use one of the trigger sounds mentioned above)

The last two could be combined into a single 3 position setting - lowest setting is 'boring', and the person's messages are silent, and possibly appear greyed out in chat, middle setting is normal, and highest setting is 'interesting', and a system notification appears for whatever they say.
