title: AirPlay API for Mac OS X
body: <p>Is there currently any API (public or private) that will allow a 3rd party Mac OS X application to stream audio to AirPlay receivers? <a href="http://rogueamoeba.com/airfoil/mac/" rel="noreferrer">Airfoil</a> by Rogue Amoeba Software seems to be able to do this, same goes for Erica Sadun's <a href="http://ericasadun.com/ftp/AirPlay/" rel="noreferrer">AirFlick</a>, but I was unable to find any source code that would demonstrate how to do this. Any pointers are appreciated!</p>
