The VNC server is more flexible than OSX integrated VNC server allowing client to connect using less than millions colors improving reactivity when connecting on a machine.

It has a lot of option and can be started from the command line which is nice if you don't want to have it running all the time. (you can log in through ssh to start it when needed)

The server is advertised on the website a a free product (only the viewer requires a license) but it is periodically trying to connect to the port 80 on my machine even though there is no update autocheck functionality...

Why on earth does it need to access port 80 for? This is an extremely upsetting and suspect behavior.... :-(
