I've just got an answer to the message i've posted yesterday. The author didn't knew me multicast vnc work and that reminded me that I didn't mentioned this tool at the mailing list. There is a tool for teleteaching available: http://WWW.Informatik.Uni-Trier.DE/~ziewer/ It's a java vnc viewer that sends all incoming messages from the original vnc server as multicast datagrams. The tool can record the session, too. The multicast clients are viewonly client for the students. The teacher works with the proxy or any other vncviewer like any normal vnc session. So you can use vnc for teleteaching right now. Let me know about interest and experience.
