The model has basically just one parameter, the propagation time - if that goes down, so can the fee. (Well there is another parameter too, the time btw blocks, which currently with the current hash acceleration is more like 400 than 600). Also seconding Mike, that, yes, it would be tremendously useful to track propagation times and other things on the network to help us all decide the proper settings. Finally, it would be great if someone from academia would grab the ball and do the full probabilistic analysis based on my outline.
