It's called comp.os.misc, BTW!

Well, all these features are implementable, but putting them all in makes
the filer rapidly bigger and slower! Therefore, I would suggest opting
for a simple architecture, but with a well defined extension system.

EG, a file header has an optional field specifying a monitor module. This
is a DLL that is notified of all access to the file. It can refuse access,
if it performs an authentication role. It can log access. It can do all
sorts of fun things like that.

It's flexible, and it's optional.

How about it?
