Well, remember that jabber is more than IM.
It's an XML-based platform for sending information in real-time.
Some ideas for integration are straightforward. Like - when you read a bboard page, the user's status (currently online/offline) could be rendered into the page; a single click would initiate a real-time chat with that person.)
Or, a slightly more complex example: Say you requested e-mail notification when a new message was posted to a bboard, indicating that you are really interested in what's going on with this particular thread... You could have jabber notify you in real-time of a post.
Even more interesting, you could have the system set up so that all the people who wanted to be notified could be part of an automatically generated real-time chat room, focused on the particular bboard topic.
(that is, clicking a single link would allow you to initiate or enter a group chat with all interested parties.)
these are just simple examples; i'm sure that people who are more creative than me can come up with interesting applications.
