Many are familiar with the “Screen Sharing” feature in MAC OS X. It allows you to connect remotely to the desktop of another MAC when that other MAC is accessible as a network share and has the Screen Sharing feature enabled under the Sharing setting in System Preferences. A “Share Screen” button will be displayed to the left of the connnect/disconnect button for the network computer in the upper right of the finder window when that remote computer is selected in the network page or in the sidebar.
Unless… If you have a network with multiple subnets, routers and/or firewalls. Network discovery services like DNS and Bonjour may not get through these boundaries. Then you may not see the “Share Screen” button, so what do you do?

This method uses Safari to launch Screen Sharing via the http port.
