Update: We are finding some setups like Qtopia the IPAQ do not allow
mouse input via uinput. Please help us debug this problem by trying
x11vnc on your device and letting us know what does and does not work.
Q-95: Now that non-X11 devices can be exported via VNC using x11vnc,
can I build it with no dependencies on X11 header files and libraries?

Enhanced TightVNC Viewer
The Enhanced TightVNC Viewer package is an attempt to add some patches
to the long neglected Unix Tight VNC Viewer. It also adds a simple GUI
for Windows that automatically starts up a STUNNEL SSL tunnel for SSL
connections to [1]x11vnc (or any other VNC Server also running STUNNEL
at their end), and then launches the Windows Tight VNC Viewer. A
wrapper and gui for SSH connections is also provided.

For Windows SSL Viewer support is provided by a simple program
For Windows, SSL Viewer support is provided by a GUI
Windows/ssl_tightvncviewer.exe that prompts for the VNC display and
then starts up STUNNEL followed by the Stock TightVNC Windows Viewer.
When the connection is finished, you may need to manually stop the
STUNNEL program by clicking on the icon in the System Tray. If it can
track the STUNNEL processes it will ask you if you want to terminate
it.
The GUI has other useful features. When the connection is finished,
you will be asked if you want to terminate the STUNNEL program. For
SSH connections from Windows the GUI will use PLINK instead of
STUNNEL.
Hopefully these binaries will make it convenient for people to help
test and use the [4]built-in SSL support in x11vnc. Extra testing of
this feature is much appreciated! Thanks.

If the uinput device has an absolute pointer (as opposed
to a normal mouse that is a relative pointer) you can
specify the option "abs". Note that a touchpad
on a laptop is an absolute device t some degree.
This (usually) avoids all the problems with mouse
acceleration. If x11vnc has trouble deducing the size
of the device, use "abs=WxH". Furthermore, if the
device is a touchscreen (assumed to have an absolute
pointer) use "touch" or "touch=WxH".
