Thoughts about VPN

[Andrey Batyiev]

I was trying to understand how is better to get VPN connection settings (ip 
config, dns servers, routes etc). There are problems: KNM/solid doesn't have 
needed infrastructure and NM doesn't provide simple way to get this info 
(there is no org.freedesktop.NetworkManager.IP4Config node, as with any non-VPN 
connections).

My solutions:
* KNM/solid: introduce VPNNetworkInterface similar to other NetworkInterfaces. 
Reasoning: in fact, each of VPN plugins creates underlying network device, 
e.g. ppp0 for pptp, tun0 for openvpn and vpnc.
* NM: we can ask NM guys either to make 
org.freedesktop.NetworkManager.IP4Config node, or to catch 
org.freedesktop.NetworkManager.VPN.Plugin.Ip4Config signal from VPN plugin.

What do you think?
