Right, that's the way it should work.  If talking to NM fails, the app
should either (a) assume a connection, or (b) could be more intelligent
by asking SIOCGIFCONF/netlink for interfaces, and if at least one
interface is IFF_UP | IFF_RUNNING and has an IP address, then try.

But only by using NM can PK really do things like "don't update while on
3G" and such which would be quite a bit more difficult without NM.
