How about adopting an architecture that incorporates special-purpose security safeguards into the CPU? Routers and switches don't need to execute arbitrary code, Cisco knows ahead of time, before they deploy a product, what code that product should be allowed to execute.

But how many times over the years has a IOS upgrade added a useful feature? .. securing the physical hardware to not accept new (aka: 'arbitrary') code would make a *lot* of rack-mount paperweights.
