While I'm not one to criticize companies flying teams out to Tuscan villas - something I'd be very happy indeed to see become the next big fad - it isn't clear to me whether the authors realize their expirement contributes nothing to the current debate about remote workers. In this case they've actually made their team less remote if you're defining "remote" as "not in the physical presence of their colleagues" (presumably with no home to return to at night or non-work friends in the area, their Italian getaway is resulting in more face-to-face time spent with one another).
