1) once an app discovers another app it needs to establish a session in order to communicate with it. 2) Yes, UNLESS you wish to discover other applications 3) notification of what? The notification service (NS)? NS does not require discovery as it is explicitly intended for applications that simply wish to notify arbitrary other applications about some piece of information. A good way to think about this is like the notification bar on your mobile device. 4) Events are signals that have meta information associated with them, and do not require the use of the NS. The NS allows the exchange of more right information, an event is inteded to convey just what it implies: an event.
