San Francisco is doing its first STV based election. If it catches on we
will see a significant increase in the number of bits required to
represent a ballot.

There have been times when ballots here in California have had on the
order of 40 to 50 races and questions. If even a small number of those
start using ranked counting methods the bit count is going to get rather
large.

And a message digest, needed for digital signatures, is going to consume
at least another 16 to 32 bits.

To me the 2D stuff is a no brainer - it gets nearly two orders of
magnitude more bits at no real increase in software cost and only a tiny
increment (an increment that may fade away over time) in hardware cost.
