Yes, the 1.2 version of TigerVNC has benefited from my extensive research into optimizing the Tight encoder to achieve the best possible mix of both compression ratio and performance. It now behaves identically to the TurboVNC server with respect to how it encodes images. You can read more about it here: http://www.virtualgl.org/pmwiki/uploads/About/tighttoturbo.pdf and here: http://www.virtualgl.org/pmwiki/uploads/About/turbototiger.pdf > Another scenario is support mode when the connection from the remote machine > is made back to my computer directly over the internet (tunneled via stunnel > with certificates - the encryption mode of tigervnc uses too much cpu) - the > other way around is not feasible because of the remote sides firewalls.

To be honest, x0vncserver is something of an afterthought, meant as more of an example of how to write a simple VNC server around the TigerVNC infrastructure. Users of modern Linux systems typically build a version of TigerVNC specific to their Xorg installation so that they can use TigerVNC as an Xorg module. I don't think this supports reverse connections either, however. If x11vnc supports reverse connections, then you can build a version of it with the TurboVNC codec, which should give you similar performance to our TigerVNC 1.2 server or the TurboVNC server, by applying this patch: https://sourceforge.net/tracker/?func=detail&aid=3394218&group_id=32584&atid=405860 x11vnc is specifically focused on that type of solution, so their product will inevitably be better than ours, since we are focused on Xvnc. I am trying to get them to accept the above patch so that anyone can build a Turbo version of x11vnc and libvncserver. ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.
