What, exactly, is the "JOS" system? Could one of the people who have
mentioned it explain, and in the future could proprietary or trade
name usage be accompanied by a description, list of constituent
materials, etc?

    **** Moderator's comments: I strongly endorse this suggestion.
    Even if a product is well known within a given specialty, please
    remember that there are many specialties and disciplines
    participating in the DistList, and interdisciplinary
    "cross-fertilization" is one of the purposes behind this forum.
