Existing Plugins/Updates for Central Managment of Client Properties/Status

I see you can use Spark as a kind of “office status board” with the status message text. Is there a way to centrally manage the predefined status messages available to the client?

Also, is there a way to display the offline users in their respective group instead of the offline group? Finally, is there a way to centrally manage the client preference settings?

I don’'t have much programming experience with XML/jabber/java, so I was really hoping a plugin might already exist. Any ideas??

thx in advance.
