I figure that somebody acted. Somebody wrote code. Is it shipping? I have a product I'm dying to sell this way right now. I'd like to hear something about this. If you don't want to talk about the product or it's means of delivery, fine. We're talking finance here now. My questions are: Total yearly expected revenue -- gives an idea about how much revenue is available to create intermediation. Distribution of buyers of the transactions -- is this more like a vending machine or a subscription service? A question of relative efficiency between identifier systems and cash systems. Total number of transactions -- gives an idea of the cost per transaction and the amount of capability to provide that number of transactions. Distribution of the amounts of the transactions -- are the amounts fixed, clustered, flat, or what? This also affects the relative efficiency of various systems. Distribution in time of the transactions -- another cost-to- rovide figure; peak load is important. If you don't want to discuss this in public, I also understand. Eric
