Is the traffic directly related to the pixel density? ie 1280 x 1024 has
about 50% more pixels. Does this mean the X stream will be 50% larger?
This will be a consideration if I put 30-40 clients on the same network.

I can turn the color down to 16 bit if that helps. 

Also, any idea how much more server resources it would take?
