Yes, generally the network traffic and the client VRAM requirements
are based on the number of pixels times the color depth. 1600x1200 is
four times more pixels than 800x600, and going from 16 to 32 bits of
color would also probably have the same impact. Since X is fairly low
level (IIRC), increases in either pixels or color depth will have a
relatively proportional impact on the LAN traffic. Feel free to
correct me if I have anything wrong here.
This is not exactly correct. Most of the X telegrams are not "pixel" based. The pixmap messages are for transferring icons and for graphical applications. So if your students are using image intensive or graphical applications, like tuxtype or tuxmath, it will have to transfer lots of pixel based telegrams to the clients.
