Plan9 is a very interesting system, including its file system view of the world.
There is a lot of history there, in all aspects of the system.  Well worth
the time for anyone to study. (Yes, it is alive and well and in distribution.)

I have never implemented a complete file system, although I have been using the
catalog generator to index my off-line storage for years.
So I can't make a comparison and contrast of what I have done with that of Plan 9.
(I have a working copy of Plan 9 installed here, it is my work that is incomplete.)

I do not know what the background of Jun Okajima's work is; just the similarities
that I can see.
