Darn, I pulled myself back into this discussion (I hate when I do that :) ).

First I will address Dann's comment:

I think the FIDE rules indirectly imply that a move must be made (although
Miles/Reuben got away with a draw with no moves in 1975), depending on
interpretation: "The game is drawn upon agreement between the two players during
the game. This immediately ends the game". Since this says "during the game", it
implies that the game is actually being played (or one move has been made???).

For computer chess, the game normally does not start until a move is made
(although I do not know how this is handled in the WCCC for if one computer is
down after start time or something).

Next I will address Dave's comment:

"Ng1 isn't an inferior move if neither player can win and they both seek the
shortest draw, which is precisely the condition I was describing.  Then it
deserves a double exclam."

1. Nf3 Nf6 2. Ng1 may be a drawn position. If it is, it may be that black will
play Ng8 in an attempt to draw. However, since Ng1 gives black two tempi, it is
more likely that it a winning position for black than the original starting
position is a winning position for white (i.e. two tempi vs. one tempi).
Therefore, there is a more substantial chance that black has a forced win after
Ng1. If this is the case, then white should not play Ng1.

If at best black has a forced draw after Ng1, then Ng8 could lead to a fast draw
as you claim. However, you also stated that maybe minimum draws are not
necessarily best (your opponent has less of a chance of making a mistake). A
more complicated or slower draw may be best. So, regardless of whether Ng1 leads
to a win for black or a draw for black, Ng1 should not be moved since it lowers
the chances of your opponent making a mistake (by trying to minimize the number
of moves of a draw AND by giving your opponent two tempi). Some different
drawing move that does not lead to a possible win for black or leads to a slower
or more complicated draw should be made.

KarinsDad :)

PS. I think I got you with my logic this time Dave, but I'm sure you'll think of
a way to squirm out of it. :)

PSS. I guess you have convinced me that the minimal draw move may not be best
(with the caveat that it may be best in time pressure).
