Mozilla Presence provides a measure of a users liveliness to applications the user has chosen to share it with as well as a system that allows for lively notifications to be delivered to the user regardless of if the application is running.  An application in this context is not the local application but a server application that Presence can contact on the Internet to convey the liveliness of users to. Server applications are assumed to have a website that can be 'installed' or a FFOS application counterpart that interacts with them.
