Parental Monitoring Software For Your Mac.
ChatCop is an easy to use parental monitoring solution for iChat. ChatCop works by watching iChat sessions for trigger words then issuing a violation when a trigger word is detected. ChatCop can email you every time there is a violation including an audit of the conversation and even a mugshot of the offender.
Demo for Mac OS 10.4 (Tiger) and 10.5 (Leopard).
