what OS? for windows you could throw http://www.actualkeylogger.com/ on it. put a few different ones just in case....and be sure to test it out before you count on it. as an after thought i would also put some kind of ssh client on it or (if windows) open up multiple remote connection on it. then when you see it on line if you need to get to your "real" data you can unknowingly log in and transfer your data (recent picture you didnt have time to back up) to a safe place. while you could just jump right on with logmein or teamviewer, the target will see this interaction and freak the fuck out.
