Whoops, just reread your previous comment and somehow I missed the "no outbound traffic" part. That would indeed seem to largely eliminate the issue, although I wonder how long it will be until devices start communicating with each other wirelessly to exfiltrate cached data. I realize that last sentence sounds paranoid, but nonetheless it would already appear to be well on its way to a home near you. For example (http://www.m-87.com/ http://www.m-87.com/), > Our software for the Internet of Things creates a Proximate Internet, intelligently discovering and connecting edge devices when they are in offline environments with poor or non-existent network connectivity. This opens up new edge networking solutions for data trapped in IoT sensors, controllers, or mobile computing devices in challenging environments. I'm willing to bet your cell phone has a data connection, and while I'm sure yours is running LineageOS or an equivalent, what about that friend you invited over for dinner later?
