So the process would be something like...

    Voter would:
        1. fill in the ballot form;
        2. sign with an unknown key (Optional, for voter verification);
        3. sign with their known key;
        4. encrypt with the voting system's key... maybe;
        5. send the message to the voting system.

    System would:
        6. receive the message;
        7. decrypt the message;
        8. check the signature on the remaining message, and then strip it out;
        9. ignore the verification signature (is this a step?  I did nothing ;-));
       10. interpret and count the vote (enter the multiple independent programs);
       11. hash the ballot paper to create an ID for it;
       12. store the ballot paper with its ID, cross the voter off the list, and
           increment the counts, in a single transaction;
       13. send the ID back to the voter, possibly encrypted to their public key,
           as the confirmation.  Actually, you could send back the entire ballot
           paper if you wanted as well, as long as it was all encrypted to their

At any point, a person who knows the ID of a ballot paper can verify that it's
in the system, by typing in the ID of the paper.  The system would lookup the
database, and show the ballot paper, which would have a signature on it.  Anyone
could type any ID and see any paper, but this wouldn't seem to be harmful since
each voter can only see their own signature. :-)
