RemoteBox is a VirtualBox client. In essence, you can remotely administer (ie over the network) an installation of VirtualBox on a server,
including its guests and interact with them as if they were running locally.
VirtualBox is installed on 'the server' machine and RemoteBox runs on 'the client' machine.
RemoteBox provides a complete GTK graphical interface with a look and feel very similar to that of VirtualBox's native GUI.
If you're familiar with other virtualization software, such as VMWare ESX, then think of RemoteBox as the "poor man's" VI client.
