NetMeeting and pcAnywhere hook into Windows at a lower level than
VNC. This involves writing device drivers and other nasty stuff, and
that has not been done (yet?). It also requires possibly licensed
Microsoft Windows DDK software.

Please read FAQ #57: "Would things work better if you compressed the
stream?" at <http://www.uk.research.att.com/vnc/faq.html#q57>

This is to prevent being interfered with when you are doing remote
work. It is great for network administrators who want to do something
on a remote machine, without being pestered by the user on the other
side. :)

Not likely, your network connection will almost always be the
bottleneck. Your AGP graphics card can communicate with the system at
speeds of (very roughly) 100 Mbytes/sec, while your network
connection is at most 10 Mbits/sec with a cable modem (unless you
have a very good cable provider, impossible in the Netherlands ;-)

Please read FAQ #49: "How do I make VNC go faster?" at
<http://www.uk.research.att.com/vnc/faq.html#q49>
The short answer is: use 16-bits (high colour).

There is no difference between a "video card" and a "graphical card".
These terms normally designate the same thing, namely a card in your
PC which displays output on your monitor. What do you mean exactly?
7. What is the reason that some users do not see a VNC icon in
the System tray when they start WinVNC?
Maybe they have downloaded a version which allows you to disable the
icon? I normally always have an icon when I start the VNC server.
