A more interesting demonstration is:
Have the program behave correctly for a few minutes/hours then change 
behaviour for some reason (like the first time somebody vote:
"4>11>10>9>8>7>6>5>3>2>1" and after that 10% of the vote are attributed 
to candidate 4) or a timer.

It is interesting/important for the Belgian situation were sample 
magnetic card are created to verify the system behaviour... then the 
election start.

So if someone want to hack the system, he need to make sure the fake 
software behave like the original for the fist hour. ;-)
