Ok, but then what is the purpose here? "Tabulation" is well within the capability of unaided humans. In fact for basically any voting technique you can name, humans will be *better* than machines at tabulation. ("better" meaning: more accurate). Machines don't have brains. Brains can sometimes be necessary to tabulate someone's vote correctly. (Voters (because they're humans) sometimes do odd, unpredictable things with their ballots-or-whatever-is-being-used, which can confuse machines, yet can be easily understood by other humans.)
I see only two benefits then:
1. We know the outcome slightly faster (whee!)
2. We get to say that we use computers & technology.
Oh, another one, I guess:
3. Government contracts for one or a few tech firms.
Call me less than convinced.
