Pre-Book Client automates the booking of PCs and enforcing time-limits on these computers. This software is ideal for libraries, Internet cafes, cybercafes, and kiosks. Pre-Book Client has three components: Windows Client, Linux Server, and Linux Client (DiscoverStation). The client logs out users out automatically once their time is up, and offers a count down clock showing the remaining time. Users can log-off either using the standard Windows log-off or use the log-off menu from the Pre-Book system tray icon.

Clients communicate with the server via XML-RPC. The Linux-based Pre-book Server tracks usage for clients across multiple locations and lets users reserve PCs in advance from a Web page. The server also enforces the usage policies set by the administrator such as maximum usage per day and many other settings.
