CarbonKeys is an open-source server/client suite containing a trojan server that records keystrokes on the infected host and a client that is able to connect and communicate with the server to download keystroke logs as well as screen shots on command.

The new version (1.3) adds a function to download screen shots. I recieved an e-mail regarding adding a feature to change where the logs are stored on server machine, so 1.4 will add that. The next update will also probably add serious upgrades to the user interface to make it slightly less confusing and more compact.
