Mike, exactly.
We're CONSTANTLY at odd with the network group, them saying Crestron doesn't know what they're doing (outside supply issues, they do).? We have this same issue using NDI for our video productions.
For a typical classroom, we won't even think about NVX. If we do us NVX in, say, a conference room or split room, we'll put all Crestron on it's own switch behind the processor's control subnet.
