The one thing identified as “the big idea” of Unison seems to me to be conceived as a solution to a distributed computing problem that incidentally also solves a number of problems that are issues outside of distributed computing (but also within distributed computing, such that fleshing out how it can solve them enhances unison as distributed computing solutions as well as providing side benefits.)
