yeah cos they're probably on bebo or playing games. At least when they are supposed to be looking at the data screen, you can vaguely tell which ones are looking at the presentation. Also your suggestion presupposes all the kids have laptops and that there is enough bandwidth in the network (which is probably wireless if they're all laptops) to do VNC to all of them. I tell you there probably not enough bandwidth, vnc is slow enough for one client in my wireless G network. multicast VNC? I wonder?
