How to capture keystrokes and messages from a Mac?

[Evia]

I am looking for some software that can capture keystrokes and messages from a MAC and i can monitor from a remote computer because of my 7yrs son is always addicted to computer. While I often go to work and have no much time to accompany him, so I want to check what he usually do on the Internet. Well, I have hunted so much on the Internet and feel that Mac Keylogger and Mac Spy are not bad. But I want to be sure which one suits me more and if it's worth my money. Do you guys use it before? Or have better choice?

Hi

Basically what you are asking for is spyware and we couldn't get involved with discussing the merits of any sort of malware on the forum.
