+Subject: [PATCH 3/3] dbus: request a name on startup
+
+When the service thread is ready, ask a name to dbus
+The advantage of doing that is that client applications
+can check dbus for bluez-alsa presence, without having
+to implement any kinf of polling logic. Also, this
+way, they can be notified on the service exit, to
+perform any needed cleanup.
+Since there must be an instance of bluealsa daemon
+per hci device, the dbus name will be
+'org.bluez-alsa.hci0', 'org.bluez-alsa.hci1' ...
+and so on.
