That works, indeed. Maybe Someone™ should develop a small "UGID server" which integrates into Debian's `adduser/addgroup` system (i.e. those tools would first ask the UGID server if that user has already been allocated an ID and if not register a new ID for it), so you can run such a server locally and tell Debian to use it so that all your machines share the same UID/GID namespace.
