Sorry to butt in, but I used to be a filesystem developer in a
previous life, working on archive storage for things like medical and
financial data. Pet peeve:

  WORM is Write *Once* , not Write *Only*

"Write only" storage is easy and fast - just throw things at /dev/null
and they can never be altered (or read back).
