=== How do I setup a D-Bus Tube? ===


Let's first look at what conceptually happens to make activity sharing work. The diagram below shows two instances of the same activity: the "Sharing Activity" and the "Joining Activity". The sharing activity is the activity that is initially run and shared with other buddies. The "Joining Activity" refers to other instances of the activity that are created once buddies decide to join an activity that has been shared. You can allow an activity to be shared (making it a sharing activity) by  [[DevelopmentTeam/Almanac/Sugar.presence.presenceservice#How do I share an activity with other buddies in my neighborhood? | including the standard Sugar Activity Toolbar]].
