I've never walked out of an interview, but I wish I had. If it's not going to work, it's not going to work. I've gone into in-person interviews with reservations, because sometimes my impressions are wrong and it's good to keep an open mind. But if it's beyond all doubt that it won't work, end it. Even if you've received a personal recommendation from a current employee and don't want to make him look bad, it doesn't matter. You're wasting everyone's time by continuing. I had this happen to me five years ago with a terrible interview process--embarrassingly unprepared interviewers, clueless HR, arrogant VP of engineering. They offered me the job and told me to go by HR, but I just walked out because I was so angered by the entire experience. There was no reason to let it get to that point, though.
