Good article but incomplete in my minds : you benchmarked programming languages whereas GPIO implementations... for example, just make a loop with print/echo in each languages and you will certainly got shell < python < C that's it, C have better IO throughput than anything else. you have to add som...

if you only need audio, you can install shairport on a vanilla Rabspian :

You may take a look at http://lcdproc.org/ which can control serial LCD screen. It can also control HD44780 throught the LPT port. I think it can be modified to use the GPIO instead. I'm also thinking about a LPT driver which will use the GPIOs... It appears that some people already connected an LCD...

I know AirPlay is fully integrated in RaspBMC and openELEC, but they both require a dedicated distrib and configuration with many features that can be useless for some users. With AirPi (and shairport), you have a simple way to setup AirPlay audio on the official distrib, without pluging any display...

I'd like to edit my initial post to precise this is a tutorial, but I can't do it

Hi guys,
I wrote an article on how to make an AirPlay audio player using a RaspberryPi without display, keyboard or mouse plugged in.
I hope it will help some users

You can also try by using the hostname raspberrypi directly if you have a decent DHCP server on your local network.

Correction, for my previous message : it's raspi-config (with and i)

Use a network scanner to find your rasp's IP !
I suggest Fing if you have an iPhone.

With Raspbian "wheezy", ssh is enabled by default.
Just use rasp-config command after the first login.
