OK, basic system behaviors?

Paper with electronic backup. Legally the paper ballot is indication of
voters intent. The CD and memory stick are backups and independent audit
trails.

'Poll watchers' is usually the term of the art.

That makes a little more sense.

Let us not forget ADA compliance. Vision impaired voters would interact
with the system via voice prompts. Motion impaired, a la Steve Hawkens,
could respond via voice prompts and air puffs or other widgets.
