I think that if the programmer is forced to send the exact program then the best chance is to send a program that is not deterministic and it's evaluation function is going to be slightly different in every game. If you decide about a special evaluation for the day of the match then kramnik may complain that he did not get the exact program but if the decision is based on luck when even the programmer cannot know the exact evaluation before the match then it is clearly the same program. The evaluation of Fritz may be dependent on the time that kramnik used for the first 3 moves in 1/1000's seconds from Fritz's point of view(it includes also operator time) and kramnik has no way to predict it.
