    Use cases of the binder afb-daemon
    
+
+
    This section tries to give a better understanding of the binder
+usage through several use cases.
    
+
+
+
    Remotely running application
    
+
+
    One of the most interresting aspect of using the binder afb-daemon
+is the ability to run applications remotely. This feature is
+possible because the binder afb-daemon implements native web
+protocols.
    
+
+
    So the figure binder, basis would become

    Adding native features to HTML5/QML applications
    
+
+
    Applications can provide with their packaged delivery a plugin.
+That plugin will be instanciated for each application instance.
+The methods of the plugin will be accessible by applications and
+will be excuted within the security context.

    Offering services to the system
    
+
+
    It is possible to run the binder afb-daemon as a daemon that provides the
+API of its plugins.
    
+
+
    This will be used for:
    
+
+
      
+
    1. offering common APIs
      2. 
+
    2. provide application’s services (services provided as application)
      3.

    The plugins of the binder afb-daemon
    
+
+
    The binder can instanciate plugins. The primary use of plugins
+is to add native methods that can be accessed by applications
+written with any language through web technologies ala JSON RPC.
    
+
+
    This simple idea is declined to serves multiple purposes:
    
+
+
      
+
    1. add native feature to applications
      2. 
+
    2. add common API available by any applications
      3. 
+
    3. provide customers services
      4.
