iTunes notifications over a network?

OK, this is a problem that has been puzzling us at Rissington. The four of us play music from iTunes to an office stereo, via AirTunes. Our music is all scrobbled, and lots of our apps use the Growl we’ve installed. It should, therefore, be easy to get some sort of notification of what is playing to all of us.

I know what you’re thinking, we should talk to each other, and simply ask whoever it is that’s broadcasting what you’re listening to. Well, yes, that’s what we do now, but it feels like all the pieces are there for some slick system, it just needs something to tie it together.

We’ve tried a few solutions, like applescripts to send updates to a twitter account, and the closest we’ve come to is the Network notifications in Growl, which does work. It works too well in fact, and now everyone gets notifications of files uploaded in Transmit, or new feeds in NetNewsWire.

Also, if anyone had any ideas of how to create a global ‘pause the music there’s a phone call’ button, I’m all ears! We once managed this by using Old Faithful™ as the sole music provider but that didn’t quite work out.

Can anyone can point us to an app or script or something to achieve this?
