Hello,
This is a little utility allows you to stream audio from Itunes /Iphone4 library to your N9/N950. It is an adaptation of Shairport. Credits to the original developer.

It has a couple of dependencies such as Avahi-daemon (a stripped down version), Avahi-utils, libdaemon, libao4 and libssl, dbus (which should be on your system already).
The application is still a little bit on the rough edge (background terminal running, but works really great and sound is excellent provided you have a good WiFi connection on your network. There are a lot of room for improvements

Install the following in this order: libdaemon, avahi-daemon, avahi-utils, libao4, meeshair.
A reboot is necessary in order to activate the avahi init daemon.

After you're done, just fire up MeeShair icon on your N9 and on your Itunes/Iphone select MeeShair as the audio output.
