It’s been quite some time since i’ve checked this thread – for some reason the forum gave up on notifying me of any replies!
In my original post i neglected to mention that for me the playback would indeed be via an Apple AirPort Express, so there is no need to consider enabling “local playback” as previously mentioned in this thread. That said, I can imagine that there would be some work required to enable FireFly to recognise the Apple AirPort Express on the network and stream to it, as iTunes is currently able to.
