Are you sharing iTunes music?
If so, have you ever wondered what external users are listening too. About the only info available from iTunes itself is when you attemp to quit and it complains telling you someone is connected. I found this freeware program called iTunes Monitor that shows you who is listening to what. It is quite simple but still useful. My only complaint is that I wish it could be integrated with iTunes so I'm not required to have an additional program open. Anyway here is a screen shot.
