@Charles Stanhope That's a good idea, I don't know. I'm not really sure what kind of information is being sent across the wire.

It might be an interesting experiment for someone to do a network packet dump in their household where they have various devices off, or on but with no known network activity applications running, and seeing if any packets are running across the wire, what, and to where.

It might be most valuable to do that at a layer between the router and whatever modem is being used, as a dumb network dump.

I'd be very interested in the result of such an analsyis.
