Concurrent Lists

Rules about Lists
     Crafting data solutions is all about creating lists.
We make lists of lists of lists.  These lists are various
aspects of our creation.  And even the items on the lists
are also lists.  We have a list of directories or
objects within the cloud.  We have a list of graphical
components that make up an entity within a video game.
We have a list of directories in which to find our
website media.
Lists of lists, abstraction of lists, creation, deletion,
editing, saving, copying or lists . . . 
In the most basic sense a 'file' is a list of numerical 
values.  A program is a 'list' of memory address spaces.
The list is a basic building block of so many things.
This is true even outside of software.
  An appartment building has a list of tenents.  But the
appartment building is not a list.  Software is not
a list in the same sense.  But the lists are there.
and the creation of other lists is part of what people
hope to do with software.  For example don't most
software companies want a list of paying clients?
With their software . . . they hope to have such a list.

   One comes in.  He gives his five dollars.  He takes the
software.  He lets fifty people copy it . . . 
   OK.  One comes in.  We will charge him fifty times five
for the software so, that way, we don't care that he lets
fifty people copy it.
   Alright.  We will sell to the government.  We will make
them actually pay a license for each copy.  But we will charge
the fifty times five for each copy!
  question:  Which software companies had this as part of
their business model?
