 * Exploit faulty permission checks so that normal apps can send or receive messages
 * Force a part of the software to emit messages
+In Gecko, components can inherit from mozilla::ipc::UnixSocketConsumer and then use BroadcastSystemMessage to send out system messages. For example BluetoothHfpManager does this:
+ gecko/dom/bluetooth/BluetoothHfpManager.cpp
+void
+BluetoothHfpManager::NotifyDialer(const nsAString& aCommand)
+{
+   nsString type, name;
+   BluetoothValue v;
+   InfallibleTArray<BluetoothNamedValue> parameters;
+   type.AssignLiteral("bluetooth-dialer-command");
+   name.AssignLiteral("command");
+   v = nsString(aCommand);
+   parameters.AppendElement(BluetoothNamedValue(name, v));
+   if (!BroadcastSystemMessage(type, parameters)) {
+     NS_WARNING("Failed to broadcast system message to dialer");
+     return;
+   }
+}
