Initiative here was to turn on & off VyprVPN as fast as possible so that it requires less attention when it comes to switching. It always happens when you are working in a company that has their own LAN network required to visit internal websites, so you have to switch between internal and external.

These are the few minimal requirements I can think of to make such a CLI utility small but complete:

• option to connect to VyprVPN(of course)
• option of disconnect from VyprVPN
• option to specify which server(ip, alias, or hostname like tw1.vpn.goldenfrog.com) to connect to(you have to change sometimes)
• option to auto find next available server location to connect to when current one fails
