WORM usage

[Mark Warren]

I am working on a specification for a driver and utility programs to handle
a WORM disk on Unix systems.  I am considering three possible operating
modes:
	1 - Mounted read-only filesystem.
	2 - Mounted read-write filesystem, with some writing restrictions.
	3 - Tape simulator supporting the normal tape IOCTLs.

Before I go off reinventing the wheel, how about hearing some responses from
others who have done this already.  Also, are there any standards groups
working on WORM usage in Unix?

I am directing followups to myself, and I will post a summary of responses
if there are interesting ones.  Thanks in advance.
