We are looking at MDQS, but still have to solve the problem of checkpointing jobs, which is just one of the mundane problems related to the way compute intensive numerical calcuations are done now. I agree, from the point of view of data compression that RCS / SCCS provide a better solution than version number schemes. But a version number system which stored diffs rather than whole files would have the same advantages in this context. I also agree that version numbering should be an option, but I still maintain that situations arrive in which keeping (in some sense) all versions of a file make sense. ----------
