i didn't look at nofollow too closely, but my impression was that (despite the name), Google would still follow the link, but not assign it any pagerank based on that particular link.
That's my feeling too. After the first publication, I email them (twice) about this, asking if GoogleBot would not follow or simply not index, and if they might consider making it no follow if that wasn't the case (or add another attribute). Never got a answer.
About the robot.txt, can we find the one used by large wiki (like Wikipedia, or others) to help Wikimedia newbie exclube spiderbot from where there aren't supposed to be ?
