Gilles, I met Tommy Guy at the pydata conference today. If I remember correctly, Brian Eoff (I don't have his email address) errantly said that random forests partitions/samples the features before creating each tree. I didn't want to correct him in front of the audience, and it slipped my mind to mention it to him later.
But I remembered when Tommy Guy asked the question.
