Agreed. The problem is, hackers don't tend to even have access to this type of problem because you need access to the very real environment of a large factory floor. And, even if you did build a better solution, there are relatively few customers, so selling is really about selling into large corporate bureaucracies, not getting someone to download a cool new plug-in. This type of selling is very expensive, and they will not buy from a couple of hackers in a spare beadroom
