I would love to see a series of pass-through "device filters" manufactured by a third party. When purchased, they can be configured to designate what is attached and then they would regularly connect to the filter service to get updated definitions. For instance, the inline filter could be purchased to be placed in between a router and a smart TV hooked up via ethernet. Then the owner configures the filter and selects the exact TV manufacturer and model that is attached. The filter device would then connect to the filter service on a regular basis to get the rulesets for that specific model of TV. The rulesets could filter incoming traffic, outgoing traffic, apply whitelists or blacklists, etc. Basically, inexpensive device-specific firewalls.
