That would totally work, and using Union mounts (http://en.wikipedia.org/wiki/UnionFS), it would probably take very little time and effort to implement. All you’d have to do is figure out how to union mount an expanding-as-needed file over the top of /users and /apps (or whatever places need to handle changes), and everything would fall into place
