Internet protocols don't care what arch you're running. Commercial software will probably be slow to catch up to architecture diversification but open source will be right at home. It's not so dire, even a good thing as it will break the US stranglehold on processor tech.
This just sounds like common sense to me. I never understood why government "secure" equipment uses foreign or public systems. I know the cost of such a type of system could be astronomical for a country but it can greatly increase and create competition for tech components. I'm at the point where if you need internet access to function in everyday society then that needs to be provided by the government and a system like the one I described could fill that void and create a lot of jobs.
