Enhanced version of VNC

Enhanced version of VNC, called TightVNC (grown from the VNC Tight Encoder project), which is optimized to work over slow network connections such as low-speed modem links. While original VNC may be very slow when your connection is not fast enough, with TightVNC you can work remotely almost in real time in most environments. Besides bandwidth optimizations,TightVNC also includes many other improvements, optimizations and bugfixes over VNC. Note that TightVNC is free, cross-platform and compatible with the standard VNC.
