Firstly, why would somebody have your root password? Secondly, why would you allow remote root log in? Thirdly, why would you be running daemons on an unsecured network?
If you want to spy on people, that's your issue. Don't install it, then, and move on. However, if you'd like to know when others are spying on you, this is a very useful utility. Doesn't sysklogd slowly fill up rootfs space with the logs, though?
Would this not be prone to high CPU usage, and leakage due to the constant polling?
