Thankyou for the info Paulus, but now I need some more help...

I looked at the help for /usr/sbin/NetworkManager and there are very few
options to specify when restarting the daemon, and the script in
/etc/dbus-1/event.d/ doesn't do much other than call
/usr/sbin/NetworkManager.

It does not seem that there is any integration with
/etc/network/interfaces at all, and that there is no equivalent way of
scripting in custom pre-up/post-down commands etc. like you can with
standard networking.

Seems like NetworkManager sits on top of standard Linux networking and
is not a functionally equivalent tool.  Are they mutually incompatible?
I suppose it will probably work to script killall nm-applet and restart
NetworkManager in a post-up/pre-down script, but will this allow me to
still hard code a specific interface in /etc/network/interfaces without
NetworkManager complaining about it when it starts up?  Eg. To hard code
the Ethernet interface, but still use nm-applet for wireless without it
complaining that my eth0 is hard coded?

I must admit that I do not really know what happens when I do
/etc/init.d/networking restart, but my assumption is that this restarts
the entire network stack (unloads all net modules and then loads them
again), whereas restarting Network-Manager simply restarts that one
daemon.  I assume that I cannot stop networking entirely with
"/etc/init.d/networking stop" and still expect nm-applet to work?
