Screen Sharing hack for OSX

Here’s an easier way to share the screens of other Macs on your network. The screen sharing feature is just an application. It resides in /System/Library/CoreServices/Screen Sharing.app.  You can drag that to your dock for easy access.

If you launch it now, you will get a box asking you for the IP address of the machine you want to connect to.  But if you want to simplify things, you can use Bonjour to show you a list of all machines on your local network.  You will need to launch terminal and enter:

defaults write com.apple.ScreenSharing ShowBonjourBrowser_Debug 1

When you launch Screen Sharing.app you will be presented with a graphical list of computers available on your local network.

NOTE:  This functionality has been removed/broken in Snow Leopard!
