Peter,

   I try hard not to be a salesman, and I understand that it's easy to
misinterpret other people's work.  However, I'm just quoting what I've
received from the publisher -- MANY ads about the Minix book that begin
"UNIX FOR $79.95?"  The ads go on to say that what you get is a UNIX system
and a text that describes it.  They mention specific UNIX utilities by name.
They talk about how it's based on Version 7 UNIX.  If Minix is not UNIX,
then the ads are just plain misleading, if not unethical.

   As for Xinu, it didn't start life as a teaching system -- it's began
as a research project and continues to be used for that.  I have several
Ph.D. students who have explored operating system design or are using
Xinu as a platform for experimental work in the distributed systems area.
It's used at other universities as well.  That's what keeps pushing Xinu
forward.

Cheers,
Doug
