Don't have much to say other than I really love and appreciate this answer. This confirms my suspicions that I'm going to like Unison a lot. I get your point, but embracing the "try to imagine a better world, even if it does mean repackaging every piece of Linux software" part of Nix makes it easy for me to see that while Unison is different, the re-imagining gets you things you didn't even know you wanted.
