I don’t particularly want to install bbpress separately. I’d quite like to extend the functionality for ‘standard’ buddypress setup.

The setup on http://help.deanjrobinson.com is good, but with various group extensions you may not want the group itself being visible to general site users. I can imagine that this will become even more of an issue now that the activty stream functionality is starting to outstrip the forum functionality – I’m finding lots of users aren’t bothering with their group forums anymore and are instead using activity stream to hold discussions.
