Hi again,

I can tell you personally that this demo is going to happen; there is no
reason we can't get there and it is too important not to.

Oh, I understand that... I just don't want to work on stuff that falls outside
the current "specs." I'll work with Fred and the other to solidify some
outstanding questions.

Here is an updated workflow, taking your comments and questions into account:

1. User verification/authentication
2. Input two witness names
3. Input voting station data disc(s) serial number(s)
4. Manual voted paper ballot count; input total
5. Voted paper ballots scanned/each ballot counted and serialized to
filesystem as XML file in <scanned ballots>/ folder
6. Collect voting station data, counting and transferring each file to
filesystem in <stored ballots>/ folder
7. Input ID numbers for test ballots that were printed on start up
8. Register known spoiled ballots
9. Compute/report errors on totals, comparing ballot count/scan vs. vote
station data:
((#4 - (#7 + #8)) == (#5 - (#7 - #8)) == (#6 - (#7 + #8)))
10. Generate/print report and ballot error log
11. Verify results and log out

Right. By serialize, I only mean write-to-disk. In thinking about the ballot
format (and I'd like to hear David M.'s thoughts on this) for both the files
scanned in and the files stored by the vote station, is there any real reason
to have these be XML? If I can simply store the data structures themselves on
disk (using Python's pickle facility), then it will be much easier to code
comparison logic. Perhaps David's xmlpickle module would work for this.
John-Paul and Jan's code would have to work with it too. Otherwise, I'll need
XML input/output formats to work with (are these created?)
