Tom, I forgot one thing I was going to say about your comment of not trusting CN network products. I fully understand these concerns. In fact, any networked device (regardless of manufacturer) that I have that does not require internet access has its "gateway" set to its own IP address. This may not be foolproof, but certainly makes it harder for malicious hardware to talk to the outside world. If I wanted to be extra cautious/paranoid, I could also add firewall rules to block devices by MAC address.
