Sounds like something that could be used for competition brewers in terms of staying within style guidelines and searching out flaws...(at least diacetyl, if your palate is not sensitive to it). But realistically, I don't see a lot of guys flocking to it. Now, if the tools were made available as a DIY project, that's another story...the same folks would spend hundreds on it.
But it is interesting, I agree on that.
