Fedora doesn't have x11vnc because it uses tigervnc which is a fork
based on tinyvnc (I think) which is massively optimised over the
original vnc. So why is that not usable? The problem with providing
copies of things like statically linked applications is that they are
then not open to the usual security updates etc. I would have thought
that gtk-vnc-python would be completely unusable in Fedora without
some form of VNC in Fedora so if x11vnx wasn't there it must have been
replaced with something else.
yum list *vnc* will show you that there's a whole collection of vnc packages.
