Jim,
I agree that it is a shame that ISO documents are not free and that the
issue of tampering is cop-out excuse.  However, the fact that you have
to pay for a standard may restrict its use in university but this is
clearly not the reason for the currently small market for OSI products.
All standards organizations charge a fee for distribution of standards
including IEEE which has written some of the most widely used standards
in existence.  I believe that OSI products do not sell well because there
are not many people ACTIVELY selling well.  If you contact most PLC mfgs
and ask for an MMS/OSI connection you will be lucky if they know what you
are talking about.  More likely they will try to convince you that the
proprietary solution is better, cheaper, etc.  The same is true for many
computer manufacturers.  The only users that receive an active sales pitch
for OSI technology are those that insist on it.
