This works for me. If you have never done it, it is a little baffling the first time keeping track of which machine you are looking at, the listening and controlling client running something like Chicken of the VNC or the remotely controlled server running Schnitz. It helps to put different background images on the machines. I was able to connect, control, disconnect and reconnect easily. The little dot cursor is OK, although I would prefer a cursor that looks like the cursor on the server, particularly for teaching.
