No you are correct. The exclusive area would have to be driven by the front end which would be tied either to a server or the protocol that Spk is developing. Thus, if it is the former, we see the immutable not being a part of what is offered to the authors. Of course, that content could be posted at a later day, say 60 days later after the subscribers got to read it.
There are a lot of ways to do it.
