Agree with Klaus here. Although there are conceptually a few areas where
read & write auditing could be useful, practically, you're swamped with
so much useless data, that finding the useful information in amongst all
the other stuff is so much of a challenge that it's not worth turning

Examples of possible positives:
* User accessed /etc/passwd in write mode... but did they actually
* Bandwidth hog needs to be identified, so look for bulk reads and
writes on network sockets.

.. but there are other ways of effectively getting the same information,
with much less system and administrator overhead (eg: tripwire, tcpdump)
- so I wouldn't recommend adding this in.
