I believe that (multiple independent systems voting on what is to
become the final result) is done fairly regularly for anything
semi-critical in aviation, at least. There, however, it's more about
reliability in the face of random errors or malfunctions than against
a determined, intelligent attacker. And of course even that doesn't
protect from anywhere near the full spectre of possible malfunctions.
