If Rob won't write User's manual of rio, fs etc, why someone in Vitanuova
can write one, and sell the books of manuals with it.   I say this, because
Plan 9 has two aspects to be considered, one is a target for OS reseachers,
and the other is a clearer base for someone, probably concerning with
education? to use it for applications.   Vitanuova, probably, targetting the latter,
I suppose.

it might be worth noting that another paper, ``A Concurrent Window System'',
is helpful in understanding the underlying model and to a useful extent the
internal structure of rio and its use of Channels (thread(2)).

Rio never seemed enough of an advance to be worth a paper.
The 8 paper describes the most important property, providing
a window system as a file server.

The only novel feature of rio is the way it avoids multiplexing
the graphics device, letting the driver do that job.  (8 muxed
all graphics ops itself.)  But other window managers can do that,
so it's not worth a paper either.
