Martin, Yes, but they are not at the same level (or price) of the iPort (right?). iPort is RS232 and bidirectional. Also, iPort also handles video iPods as well. Not sure if both of the Channel Visions do? Also, isn't the channel vision solution proprietary with their rest of ABus system? I see at least one of the CV systems is IR based?
Not sure how the CV solution would integrate with a MainLobby touchscreen UI without bidirectional data flow.
