I'd argue that your best best is to consider PC
based systems like ours, CQC. It's inherently
IP based and network distributed, very flexible,
and I'll be happy to help you get drivers done
for anything that you need that we don't currently
support. It'll end up being a lot less expensive,
and I believe that PC based systems are the future
of automation (in the same way that they have
knocked expensive proprietary hardware based systems
in many other industries.)
