Hi Frank,
os.type() returns either "unix", "windows", or "msdos".

I suppose that on OS/2 it returns "msdos".

OS/2 is collaborative work of IBM and Microsoft.  Microsoft gave it up
when Bill Gates came to the conclusion that a multi-tasking OS is only
good for mainframes, not for personal computers.  But AFAIK the most
commands work on both systems.

I don't know why you are so much concerned about OS2 and MSDOG.
None of these systems is maintained anymore for centuries.  There are
no actively maintained TeX distributions for these platforms any more.  

Stupid question: Do the old, unmaintaned TeX distributions for OS/2
and MSDOG provide a texlua engine???  This is essential if you want
to support these systems.  My opinion:  Forget them.

I suppose that Preview is part of OSX and should be used by default on
OSX.  However, it should be possible to switch to AR somehow.

All the non-Adobe PDF engines only support a subset of the PDF
standard.  A user should always be able to make AR the default

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
