It sounds to me like the request is for an indelible/immutable journal, potentially backed by a legal requirement. Think (US) SOX, Sarbanes-Oxley, requirements, or similar elsewhere. Or consider a criminal computer-related case where an investigator's every action while analyzing a suspect's drive is write-once recorded, creating a permanent record to be used in court. Or for that matter, consider the audit trail of an electronic voting machine. In such cases an indelible log that cannot be altered without destruction is vital. -- Duncan - List replies preferred.
