I believe the reason Microsoft's remote desktop is so much faster than
VNC is because it sends commands ("draw a window just here, move this
window over there") whereas VNC literally sends a picture of your
desktop (or just the changed bits). Apple Remote Desktop and Timbuktu
may do the same.
Be warned that the whole of that last paragraph was conjecture and
educated guesses, though.
S'right, though. RDP hooks in at the Windows GDI level, where the draw
commands are, and caches bitmaps etc in much the same way as a local
framebuffer. VNC is a very much after-the-fact solution, pushing
chunks of screen around the network.
Not that I have any trouble with it. Even dock-bouncing anims work
fine for me, from the Mini to my MB, all on wifi and without me
setting the colours down.
