Technology

You don't pay for the services in it. Storage, computation, bigger channels.

So yes, I think it should be possible to make paid connections to a service, like a paid phone call.

Or to buy storage.

There should be a new stack of web-like (application-layer and up) protocols. To separate requesting storage (put, get), computation (submit a task, get a result) and search (get from index by keywords) into technically different tasks and to make them paid on technical level. Probably make some procedure for aggregated payment for accessing a service. Then the service itself should be on the next level, and probably built from these services on the client.

It should be a client-side decision to "continue to a paid service for N monies".

People who've built the Internet - they were an academic bunch, or in case of Sun founders, an economically inept bunch (yes, I can repeat that ; their period of huge success was mostly when they were making workstations ; though to be honest I liked Bill Joy's interview on climate and externalia). They didn't consider this important. They made a library system for a community of peers.

That's an intermediate version of what I'm dreaming of, except what I'm dreaming of would have uniform infrastructure completely separated from content, so services would serve many applications in a uniform way, storage and computation and search and maybe message relay to another user. The applications themselves would differ from each other, and their differences would exist locally on user machine.
