I think that's a very interesting way of looking at it.
Because of the stage of the process here at the moment, by definition, you're looking at structures and statistics, how it would all work, and what it would all mean. That's an important thing to do, but in terms of the New Zealand experience, looking back on it now, I would argue that though we count votes differently, what's been more important is actually the political cultural change. For a political party to be successful, it needs to reach out to the entire country and not just see voters according to the determinant of geography. Geography is important, of course, but it's not the only thing. There are lots of other values and that forces parties to really shake up the way they campaign and think.
