I'm a foster houseparent needing to monitor four youth simultaneously to ensure they are not visiting inappropriate sites or having inappropriate discussions/contacts. We have a computer room with 5 PCs. I'd like to have four teenage boys online, and sit at the fifth PC with screen images of their four screens displayed in four small windows, while I work in another window, with the ability to zoom in and/or take over or freeze their PC if I suspect forbidden activity.
