It seems like a good idea in theory but i'm not so sure it'd work in many environments in practice. If i understand it correctly, you're storing all the state such as files but there is state that is tied to that specific machine (ie. machine fqdn, machine-specifc filepaths) and you wouldn't want to apply that state on another machine. I guess you could do some data wrangling and .stateignore that stuff but it would require quite the effort on a large application that spans many components and many teams.

On a very small app, i can see the utility of dotmesh.
