Having spent many years on both sides of a bar, I believe "the pour" creates a bond between barkeep and punter. It's as much a part of the drinking ritual as clinking glasses. It starts the conversation, a conversation we've been having for 10,000 years. Beer gave us civilization and continues to civilize us. Automation doesn't aid in that.
However, if I owned a big restaurant or chain of restaurants that served hundreds of beers each evening and patrons never saw or cared about how their beer got in their glass ... sure, I'd try it out. But that's the world of InBev and Carlsberg and I think many of the folks on this forum are here to escape that world. If you're looking for positive feedback for your machine, I don't know if this is where you'll find it.
