Without a major overhaul of the entire voting system, it seems that computer vision could assist with observation. Let's say both parties can have their own tamper resistant devices that can record their own counts of votes from a portion of ballots with identifying information removed. Either party can challenge the recorded result from a ballot and must make a deposit that is not returned if their challenge is not successful. The whole idea of having multiple humans standing around watching every ballot seems like it's unfeasible, and presents the opportunity to cast doubt on the process.
