Size is a big factor, and an important one to to watch. But we can do better than that. (Relying on a google/human translation here so maybe I got the wrong meaning...) We know much more about how to put in place trouble-limited payment systems than we did in the digicash days. There are many examples around, you can check for example the fee structure of Paypal versus the others, and wonder why Paypal fees are so high. Easy answer: they like and appreciate a floor of trouble, because that keeps fees high, and high fees means high profits. Fee structures of other systems are 1-2 orders of magnitude lower, and sustainable, because they use a lot of the techniques we have developed since the halcyon days of simple cryptographic designs. iang
