OK, but before switching away from NetworkManager, check out 'cnetworkmanager'.

NetworkManager consists of two parts...a daemon which interacts with
lower-level network management tools, and clients which communicate
with the manager via D-BUS.

In most systems, NetworkManager is controlled via nm-applet, which
shows up in your XDG system tray. You can also use cnetworkmanager,
which is a console-mode client.

I would assume there's a configuration option, somewhere, to allow
NetworkManager to configure wifi connections without a login session.
If not, it should be possible to use the console-mode client in an
init script (possibly inside a screen session?) to get the wireless
connection configured.

Probably not as elegant as having a configuring daemon you don't need
to interact with, though.
