Yeah, I've taken a similar approach - my comments were more just to raise awareness about how much verizon is theoretically able to do in light of what a low bar they have for doing them for LEO.

You can get it set up so all your iptv services work with the ONT using the ethernet port BTW - that is the default install configuration these days for people on the faster service tiers as moca caps some where north of 100mb. In that setup the actiontec is connected both via coax and ethernet to the ont, and it serves as a ethernet<-> moca bridge internally to support the ip features of the stbs.

Running the STB's without any moca is basically unusable, no epg, no dvr, no vod etc. And it's worth noting that even though my actiontec is physically separated from my home net through a tweaky setup, they could still theoretically do full stream wireless packet capturing of whatever the radio could hear, or become an active node on your other 802.11 network. Brute forcing a WPA2 secret is a common enough practice that they have purpose built luggable SFF pc's with 4 tesla cards inside for field work.

You can actually remove 100% of the verizon CPE and still good tv if you're willing to pay for it. Once I found out all the stuff the STB's are doing I'm in the process of replacing them with a tivo with a cable card and a tivo mini (basically a slave). Even slightly cheaper per month than the multiroom dvr, though the upfront is $$$
