TightVNC Features
Here is a brief list of TightVNC features absent in the standard VNC.

  a.. Local cursor handling. Cursor movements do not generate screen updates
any more, remote cursor movements are processed locally by the viewer, so
you do not see slow remote cursor movements behind the local cursor.
  b.. Efficient compression algorithms. New Tight encoding is optimized for
slow and medium-speed connections and thus generates much less traffic as
compared to traditional VNC encodings. At the same time, TightVNC supports
all the standard VNC encodings, so it can operate efficiently over fast
networks, too. Thus, with TightVNC you can work remotely almost in real time
in most network environments.
  c.. Configurable compression levels. You can choose any appropriate level
of compromise between compression ratios and coding speed, depending on your
connection speed and processor power.
  d.. Optional JPEG compression. If you don't care too much about perfect
image quality, you can use JPEG compression which will compress color-rich
screen areas much more efficiently (the image quality level is configurable
  e.. Enhanced Web browser access. TightVNC includes a greatly improved Java
viewer with full support for Tight encoding, local cursor feature, 24-bit
color mode, and more. The Java viewer applet can be accessed via built-in
HTTP server like in the standard VNC.
  f.. Support for two passwords (full-control and read-only). The server
allows or disallows remote keyboard and mouse events depending on which
password was used for authentication.
  g.. Advanced Properties dialog in WinVNC. Unlike the standard VNC,
TightVNC gives you the possibility of setting a number of advanced settings
directly from the WinVNC GUI, and to apply changed settings immediately.
There is no need to launch regedit to set query options, connection
priority, to allow loopback connections, disable HTTP server etc.
  h.. Flexible configuration options. Unlike the standard VNC, TightVNC
allows you to choose arbitrary port numbers for TCP/IP connections, in
addition to display numbers traditionally used in VNC.
  i.. Automatic SSH tunneling on Unix. The Unix version of TightVNC viewer
can tunnel connections via SSH automatically using a local SSH/OpenSSH
client installation.
  j.. And more. TightVNC features a number of other improvements,
performance optimizations and bugfixes, see change logs for more
