Cocoa VPN Connction create and connect (XCODE)

The project winner will be required to create a small app that will create an L2TP VPN Connection using SCNetworkConfiguration. Required will be on the Main menu a username and password field and two buttons, one to create the VPN connection and the other to connect/disconnect the connection. Nothing fancy just basic looking and of course the code behind it to do the mechanics. All source code is required and done in XCODE
