Er, it seems to me that you are mixing together two problems:
1. managing application bugfixes & upgrades
2. managing distributed application state
Having a whiz-bang way to manage the BEAM files required to do #1 is
usually done by copying the new BEAM files to all the places that they
need to be, then using a. load a module at a time (usually via the
console, for small patches), b. OTP app upgrade (cool but tricky to
coordinate, depending on the app), or c. rolling node stop & restart.
There are other ways to do it, as you were exploring, but they aren't
the sort of things that I'm aware of many (any?) people using in
production. (Aside from diskless/stateless embedded systems.) Or I'm
completely misunderstanding your question....
