I replied with a pile of high assurance browser designs last time you said that. Such work could be turned into a production system. It&#x27;s what Google did, actually, by turning OP Web Browser into Chromium. Weakened its security to make Chrome lightening fast. Yet, Chromium work was <i>way</i> harder to build than just getting one of these prototypes into better shape. They managed that, someone could manage other goal.<p>Besides, you can always isolate that part onto an untrusted board with KVM switch built in like I used to do. Push-button easy.
