    I have thought about journaling, but

    There's a speed-hit associated with Journaling and it happens
    at unpredictable times. (Caused only when you make changes to
    disk contents -- reading them makes no difference.) It's not
    very big, though, and you probably won't notice it unless you're
    trying to save live video or audio to disk.

    What comes to mind that scares me off
    journaling is the amount of time it takes
    to index for content in OS 9, which may
    be a different thing entirely.

    That's a difference thing entirely.
