Having worked on Accuvotee systems in the past, I concur. However, live feeds of the hand count are an absolute must. Teh shenanigans(criteria to throw out votes) that occurs behind closed doors needs exposure scrutiny.

In Germany, every citizen is allowed to watch the counting at his local election buro. I think that is what is needed, and the larger parties send one member to every single room where counting is happening. So you need to involve a lot of people if you want to forge an election at scale.
