As someone that's gone through many an Oracle audit and sit down to discuss licensing, Oracle can EABOD.
At one stage we had to rethink the CPU configurations for our new Blade's after sitting down with Oracle's own people, they then had the gall to state we had violated the licensing and we had fun and games showing them all the communications where they stated what we were doing was correct.
Then there was the audit 3 years ago where we ran the scripts, they again accused us of being wrong, we sent them communications again and then heard nothing back for two years.
Or the fact that their own installs turn just about every feature on and you have to then turn them off or they shout license violations.
