Need some sort of automation to switch to destination server without manual clicking. May be you can add functionality to your VyprVPN.exe to take a param that would specify a server to which a VPN connection is made (you can add optiona user ID and pwd). Assuming VyprVPN app is running (and a user is logged-in), when VyprVPN.exe -s us2.vpn.goldenfrog.com is launched it would do the same as manual selection of the server from the list in GUI - just establish connection to specified destination.
