Unless I am mistaken: VNC traffic is bitmap (whole screen or part of the screen, optionaly compressed) transfered at each refresh. FreeNX is compressed/cached XWindow traffic. I think, although there are bitmaps in XWindow too, you could almost think of it as bitmap (heavy) vs vectorial (light). http://en.wikipedia.org/wiki/NX_technology JD
