Sure; the intended audience for the OS itself (divorcing, for the
moment, from the Operating Environment/UI) would be developers. In
much the same sense that Java and .NET are/were touted as safe & ease-
of-use for the developer. Or, if we want to be a little more specific,
Student/Academics & Scientists; I believe that the task language-
construct could also be leveraged nicely to allow for parallelism
(both distributed and local) -- which is supposed to be "the next big
obstacle" in mainstream/commercial software.

As for a Specification Summery; I've not really done a specification
(read & implemented, yes; created, no) and so I'm a bit nervous about
trying to summarize what is rather highly informal scrawlings of ideas
in several notebooks. Though I suppose the "fundamental theory" could
be described as an anti-Unix: everything is NOT a file, they are
objects (general-sense more than OOP-sense) that should be treated as
such.

I suppose a good example would be a HTML file; sure you could store it
as a text-file, because it *IS* a text-file... but it's also a subtype
of a text-file, and could be an object of some form similar to:
Type HTML_File is New Text_File with record
  Header : HTML_Header_Type;
  Body    : HTML_Body_Type;
end record;

That example might be more confusing than I intend though; in which
case just ignore it. I'll mull over how to synopsis a spec out of my
pile of random thoughts.
