Could you clarify how you would see these batch data transfered outside of the internet ? We are speaking of dispatching that data to every single voting stations, set in schools, small town offices, etc. Most "secure" solutions (private lines, central update and physical dispatch of the machines days before the elections, etc) seem difficult and/or crazy costly to me.
