Well, first of all I think in normal games players should be free to
chose any komi they like. Of course for rated games there may be some
restrictions but on KGS those don't apply to 9x9 anyway (9x9 games are
For 9x9 computer go tournaments I would propose to use either komi of
6.5 or 7.0.
That way at least it's not a clear disadvantage to play first.

KGS implementation, area rules in general are ok, especially for
computer go tournaments because they make it easy to resolve disputes.

Well, I may have made an argument like that before, but I'm not sure
about the winning percentage of 6.5 vs 7.5 especially under territory
scoring. I do however think that, especially once you get to the level
where it is often about getting the last point, territory scoring is
more interesting than area scoring.
