Has there been any update to this issue? I am currently facing the same problem in a pre-buy situation. I have mt-daapd set as included in debian etch and can “see” it on any of my cable-connected workstations using iTunes with Windows or Rythmbox with Ubuntu Linux.
However, the server is not found when using iTunes on Windows on my wireless connected Laptop.
I am using the Zyxel Prestige 660HW-63/67 too, the System Status page says:
