Is NLU even needed? Seems like just a normal parser generator would be enough, the hard part is all the UI and integrations since there are bazillions of devices, many of which don't have a local API, some of which can't because they're cloudful inherently like Google Calendar. I think $100 would be about the limit for consumers, if that, but enough of the techies might switch to make it profitable.
