Simple Network Monitor

Ok...you have a main computer (A) connected to the Internet. But your sister wants a connection too, to her own computer (B). So you make that connection through a cross wire or a Hub, for example. But, at night, you want to go to bed - but she is still working, so you can`t shutdown your computer. Solution? Simple Network Monitor will check if her computer (B) is on or off. If it`s off after 15 minutes, it shutdowns your computer (or alerts you) , ending correctly your applications. It`s that easy.
