RFB is "remote framebuffer". Think of it as VNC's "platform".
Zarutian 2006-07-30 23:08: hmm... an simple subrect application might be in order and quite handy when you want to show someone via VNC a part of your screen rather the whole screen. (Implementation notes/ideas: four windows using same technique as spiffy caution edged window as the perimeter markers. Just pipe from an already running VNC server through the application.)
