Airplay streaming of music on Arduino Yun over wifi

Hi,

I'm new to arduino boards and have some queries ?

Motive :I want to stream music from iOS device using Airplay to Arduino Yun over Wi-Fi

Queries:

1) What SDK/IDE would I need to use with your Arduino Yun ? 2) How to debug Arduino Yun ? 3) Is there any libraries and code for airplay ? If yes, license is required or not ? 4) Does any Non Disclosure Agreement(NDA) required in the development ?

Thanks in advance
