OK. But--all things must end. If, say, you did not have a desktop component, are you obligated to keep the service up--forever? That's a long time. I wonder if--like a not-bargain price--a subscription fee is an indicator (to a different group, naturally), that you will be around--at least for as long as people pay you. Otherwise, what's to stop you from grabbing the money and stopping the service?
