Yeah, the Airport devices present themselves via the Bonjour system for
which the default Linux implementation is avahi.

So how are you actually going to talk to the Airport devices once you've
I'm a little confused as to what the aim is here considering that the
actual method to output to the airports will be very different on
different platforms (I don't know how it works on windows, Airofoil
speakers seems to be the way that it works generically on OSX and
obviously PulseAudio on Linux).
If your app just detects the devices and then uses the appropriate
systems depending on system, then this could work I guess. Or are you
planning to implement a system to output directly to the Airport device

Well I'm not sure about the internals of the Bonjour system personally,
so I'm afraid I can't really help you here.

I don't really know to be honest as I've not done any java development
and am unfamiliar with this system. Have you made sure that your linux
install opens port 5353 in the firewall?
