VNC could be very useful in training classes where students can follow
on their screen what the instructor is doing. To allow this, the VNC
viewer should handle a -readonly option to disable mouse and key
events passing from the client. The changes are very small in the
viewer code.
I've made some performance tests with the server on NT 4.0 and the
client on UNIX. The mouse handling is too slow on our fast network. I
wonder what would happen over a modem... IMHO, the cursor should be
handled separately. The cursor image should not be part of the "screen
content" which is transmitted. The server should only send to the
client the definition of the cursor (pixmap + mask) and its
position. The VNC viewer should handle the cursor image, which is
trivial in UNIX/X.
