VNC sends a copy of what is in the framebuffer, which may or may not be displayed on a physical screen. You can have a framebuffer on a machine that has no display outputs at all. You can have 10,000 different framebuffers running on the PC you're working on right now assuming you have the RAM for it. I haven't set this up recently, but I believe that's basically what x2go does out of the box (except it uses NX instead of VNC). RDP is capable of functioning without physical console attached. Consumer versions of windows may block doing much of this for licensing reasons, but certainly at work we've had 20+ users connected a single citrix server at once. -- Rich
