has more information on the architecture changes in 0.9.  One big one is
that the session applets (knetworkmanager, nm-applet, etc) no longer
store whole connections; they only store secrets.  Thus they become
secret agents instead of full settings storage services.  They no longer
need to advertise a D-Bus service.

Yes, whenever the thing that's going to respond to secrets requests (ie,
the secret agent) starts up and shuts down.

Probably the Qt D-Bus bindings, which I think is what the old KDE stuff used.

Not necessarily; you'd still need to store secrets somewhere, and the
storage files are probably as good as any.  But you wont' need to store
whole connections; just secrets.  So at a minimum you'll need to store
the secret itself, the key name of the secret (ie 'psk' or 'password' or
whatever), and the UUID of the connection the secret is for.

Usually with Qt/KDE you'd use the Qt D-Bus bindings to do anything D-Bus
related.  Unfortunately I don't know much about those, but others on
this list (like Will Stephenson and Eckhart Woerner) know the Qt/KDE
side of things.
