If there were a way to assign specific categories within those modules to users, I would think that would be ideal.
That way, for instance, you could have a user that is only responsible for (and only has access to) a specific category of calendar event, or a user that can only see/edit three news categories instead of all 50+...things like that.
We're only at BigTree v4.2.24, so I have no idea if that sort of thing has already been addressed in one of the many minor versions of BigTree that have come out since, but if it hasn't, maybe that would be something useful to do in BigTree 5?
