Actually, the problem isn't in the method OR the distribution, it's nz's fucked up internet model.
Who the SHIT pays for a connection with a download cap?!!! (NZ do, because they HAVE to.)
The flat I've just moved into have chosen a 4mbit connection over an 8mbit one - why? Because the 4mbit one is 'normal', while the 8mbit one has a cap - of 4gb / day, but with 3 gamers / 'heavy users' it isn't unrealistic at all to think we would have to watch ourselves. This thought filled us with utmost dread - and you poor fuckers have to deal with it on a daily basis (as 2 of the 3 of us in the flat used to, being ex nz / nzgamer's.)
I cried inside when I left nz, but not one of those tears was for the data caps I can assure you
