Indeed but I still feel my original point stands. If you can achieve their process half reasonably with a bodged espresso machine there's a reasonable chance it will become popular (assuming of course it does provide unique coffee!). If it's complex precision engineering even if they're directly working on commercialisation it'll be a struggle.
