x11vnc also supports native Mac OS X Aqua/Quartz displays using the -rawfb mechanism. The mouse and keyboard input is achieved via Mac OS X API's.
So you can use x11vnc as an alternative to OSXvnc (aka Vine Server), or Apple Remote Desktop (ARD). Perhaps there is some x11vnc feature you'd like to use on Mac OS X, etc. For a number of activities (e.g. window drags) it seems to be faster than OSXvnc.
