My goal in this (ADD) document is to highlight work that is related and
if possible we could design hooks into QScada for compatibility
or at the least gleaning the useful features from these efforts.
Others such as 'comedi' are more fundamental in nature to QScada.
Once I flip it (ADD) over to the  group, others would be encourage to
comment or edit the docs.  As an employee at a company that has
developed lots of embedded systems (products) the ones that are the
most successful, are the ones that have excellent specifications. The
best way to minimize costs (maximize potential) is to have a robust
specification *BEFORE* coding begins, in my experience. YMMV.

Amazing! We agree. Push RT performance requirements down to the
lowest level.  I do agree that we do not have to 'delve' into RT
issues, in depth, at this time, but, creating a high level document so we
can be sufficiently organized that when that (RT) time comes, we have
something (a stub) for folks to work from.

Excellent. When these 'early docs' are completed, somebody will
need to get us little people (like me) organized so we can begin
to contribute code.    My previous email on which software and
which versions will help the group stay compatible, at least
in the early efforts. I've picked up a book on Java and starting
some simple coding. QT is another area where I could use
a good book && examples to get a feel for QT.... Suggestions?
