HardwareMap – Lists computers,services on the local network and hardware connected to your computer
It lists computers and services on the local network (Avahi) and hardware connected to your computer (HAL). When you click a device, it tells you properties of the device and lets you perform common actions for that device. For example, an ftp share has a button to open in Nautilus, a webcam has a button to open in Cheese and an inline preview of the webcam.
