Distributing computation throughout a number of independent services across the internet is undoubtedly a good idea. Each service can be efficient specialist in one thing; and multiple services can spring up for popular tasks.
However people designing these services are hung up on payment.
- they believe that all AgoricSystems must model payment to manage efficiency
- they are trying to build a business out of these services
