If you are on the same lan as your target aim machine then you could use a program like deadaim or aimplus. These programs keep logs and you could simply share the log folder and connect to it when you wanted review the messages that others have sent to you. Or you could use a remote solution such as VNC to see your whole remote machines screen as if you were sitting in front of it. (Sorta like win2k3 terminal services except with 1 tty) This way you could reply to the messages from where they are located.
