What might be a common case today, doesn't mean that it will be a common
case tomorrow. For example, UMTS networking is more and more common this
days in Europe. I can be online wherever I am in Germany, I don't have
to go to a nearby Starbucks for wireless, I have UMTS on every park

I don't like the idea of configuring/using my common case using other
tools, which would just disable NM. NM should be a networking king, and
the one in control.

I agree that the static IP on wireless is a broken design. Static IPs
are required by servers, and since they are not mobile in most cases,
they should be connected by cables, if for nothing else, then at least
to free up radio bandwidth for the clients.

However, If you treat NM as a networking king on DBUS equipped linux
system, I can see it helping in the server configurations too. In my
point of view, all of the networking should be handled through NM.
Server cases probably don't make sense in the desktop applet, but they
definitely do in the NM daemon, and its DBUS API.

Right now, I have to start up my ppp on UMTS manually, which means that
I can stop the NM at the same time. I don't see a need for this disable
API at all.
