Hi Phil,
at the first look a great work! gratulations!
But i have a problem. I have a BeoSound 3200 an Beolabs with Wireless 1 or beoaktives in the House. No TV. My Beoport ist connected with a imac via usb ans the line in about a airport express (i know thats not ideal for the sound, but in this way i can avoid that the mac sound is streamd to my BS3200 next to the musik). My favorit Playlist in iTunes ist iTunesDJ. Actually i can control everything with my beo4 over LinkPlayer1 and also when playing N.Musik with our ipads, iphones and ipod-touchs. The important think is, that i can edit iTunesDJ (erase a song, or make whichs) while it is playing. And I can receive the Musik with non B&O Speakers (like B&W Zeppelin Air) over Airplay. Perfekt!
With LP2 i have two problems:
1) AirPlay is actually not supported
2) I can´t edit iTunesDJ with the RemoteApp on the different Devices
Maybe you can reconsider the iTunes-integration. It could be very helpfull for some of us.
