This is still being worked out, but, at a high level, it will work like this.

For a module to be usable via import from zpt, the module will have to be
registered.  There will be a UI for doing this interactively. The
registration will include information about the names that can be accessed
and the permissions required.

Persistent modules are software.  IMO, there is a need for "active content".
Software is relevent to an entire site or system. Active content is much more
specific.  For example, someone might need some Python code to support
presenting some specific information.  I see PythonLibraries as the much more
pythonic successors to "Script (Python)".
