Após algumas pesquisas, descobri uma maneira de automatizar isso no Windows 7: AutoHotKey
Eu escrevi um script para criar um arquivo de texto para sincronizar com o NAS enquanto o iTunes é aberto. Esse arquivo de texto é uma chave exclusiva do computador que o abre e só será criado / removido quando o computador em questão estiver "online" para garantir a integridade.

; the only way to keep integrity is to make sure that everything is synced before creating or deleting key
; if there is no key, only create one when there is internet connection, which is a safe bet that it is synced.

IPs := HostToIp(NodeName)
DllCall("Ws2_32\WSACleanup") ; always inlude this line after calling to release the socket connection

if IPs <> -1
FileAppend, This file represents iTunes key'n, %A_WorkingDir%\Win7Key.txt ;Msgbox, %NodeName%'n%IPs%

;if the right key exist, allow iTunes to run, and delete key only if internet is available
IfExist, %A_WorkingDir%\Win7Key.txt

Run, "C:\Program Files (x86)\iTunes\iTunes.exe"

Espero que isso ajude alguém. Agora estou procurando uma solução Mac OSX. Eu farei algumas pesquisas no Automator para ver se possível. Se alguém tiver outra solução, compartilhe.
