Thank you so much for building this and thank you so much for building this on Open hardware. I can already see a lot of use-cases for this - For example commercial complexes like expensive theaters and 5-star lounges where many people visit everyday. You have your own niche, please don't listen to any of the negative comments (like how this would improve this your life, etc.) It certainly has its place and it would be great if you could drop in your skype, I'd love to have a chat about this (Packaging, Target audience, Marketing, etc) Cheers, Neya
