You can get the same functionality without the app

Being a simple front end for the built-in VNC app, this one is pretty useless. You want to get the exact same functionality without this app? Just do the following:

Open Finder
Click on Go->Go To Folder
Enter: /System/Library/CoreServices/
Double click the "Screen Sharing" application
Right click on it and choose "keep in dock"

Thats it, no app to install.
