AirSpeaker allows you to use your iOS device as an AirPlay speaker, like AirPlayServer and shairport.
This can be useful for those who want to add AirPlay capabilities to an old iPhone/iPod dock, or generic 3.5mm speakers.
AirSpeaker runs as a daemon (system service), and therefore lacks an app icon, as it is not an app.
You may configure and use a password if you wish to do so from its preference pane.
The AirPlay speaker name is also changeable from AirSpeaker's preference pane (the default being "AirSpeaker").
