Yes.

NM offeres two ways for applications interested in network state. One
is very convenient and easy to use but because of that not very
detailed. It only signals changes when networking is disabled, (no
active connections and a) connection is activating, activated,
disconnected.

The other API is a detailed one and is what nm-applet uses, for every
change a signal is emitted. As there are many objects involved, it's a
bit cumbersome to register all these signal handlers if the
application only cares about if a connection is active or not.

So in summary, if any application (pidgin, evolution) want, they can
have a very detailed view of the state and signals when anything
changes, but as of now, they use the simple version.

See above.

See above.
