You can do w to find out what someone is running, but you can't figure out exactly what he sees. You can try a cat /dev/tty4 - which will do some weird stuff - like every alternate key he presses will show up on your screen, and the remaining keys on his, but this would only alert him to the fact that something is wrong.
Furthermore, if you really feel the need to do so much snooping, then there's definitely something wrong somewhere.
