Ron I think you may have missed my point.
I don't propose to use it like they imagine its use. I propose to use
it the OVC way (see outline in previous e-mail). Then it's not more
or less risky than the OVC touch screen component. Actually I think
it's less risky, because I suspect voters are probably better voters
and better checkers of hand marked ballots than printed or worse,
screen ballot choices.

To make one specific point: In the OVC paradigm the pen will NOT be
recording the votes. It does keep a memory of all marked ballots.
But it does not tally them since some of those marked get discarded.
It does however corroborate the creation of all final paper ballots
that are hand scanned later.
