I once wrote a memory resident keylogger back in high-school to catch the lonely sysadmin's network login. Not that I knew what to do with the login, I just wanted to prove to myself that I could. I got plenty of logins, but not the one I wanted. Until a friend looked over the sysadmin's shoulder. I lost interest right there, but my friend went on to wreck the entire network by mistake and barely escaped paying for the whole mess. Have to give some credit to the sysadmin for the catch. To figure out who was messing with his stuff, he put a program that emitted a high frequency tone through the PC-speaker in his login script and sat down next door to wait for my friend to take the bait.
