I see how that can be a problem in that context, NASA might never be a candidate for much remote work beacuse they are working on some of humanity's most complex projects for example. I just dont think a lot of work is that complex. Accounting, sales, insurance adjusters, data entry and many other office tasks are easy to quantify. My point is at the end of the day both parties need to be happy enough to continue the relationship tomorrow, I simply dont think i'd care how many hours you put in only if you generate more value then you consume.
