It would be nice to have machine-readable output for vpnutil. JSON looks like obvious choice these days.

Sounds like a great idea for the list and status options for vpnutil

@Spaider vpnutil list now outputs such a json:

{
 "VPNs" : [
 {
 "name" : "VPN1",
 "status" : "Connected"
 },
 {
 "name" : "VPN2",
 "status" : "Disconnected"
 },
 {
 "name" : "VPN3",
 "status" : "Disconnected"
 }
 ]
}
