Furthermore, if you really feel the need to do so much snooping, then there's definitely something wrong somewhere.
Not necessarily. This could be to do some sort of remote monitoring like a one way VNC session. I know of one telemarketing app that used this technique for QA purposes. It used some kind of pipe on the terminal device and rendered it using the curses library.
I'll see if I can find out more details and post them.
