Id also like to come up with a way to prevent too much hashing power from being concentrated on one copy of the history. If anyone has an idea for how this could be achieved Id really like to hear it. This would be another way of preventing the industrial miners from sucking all the air out of the room.
I talked about that in this post: http://bitcointalk.org/index.php?topic=395769.0
The only thing I could come up with is ditching Bitcoin's "infinite" wallet address solution and making it so each user only has one wallet, which makes it much easier to assign global variables to the system to cap people's possible mining rewards per day.
So basically, the "fairer" the coin, the less privacy you get unless it also implements native coinjoin or something like that.
