Short CORBA intro: 
* CORBA: a buzzword for connecting different application together.
* IDL: Interface description language. Portable description of
  an interface.
* ORB: Object Request Broker. Translates requests made via a native
interface (E.g. in C or C++) to the IDL interface and back.
* Naming Service: A CORBA thingy that you can use to find the 
application you want to talk to.

Yes. The question is indeed whether CORBA will be very usefull 
here.

I can think of a setup like:

PPP-dialer
    ^
    |(3)
    v
+--------+   (1)   
| NetMgr | <----> Non-X applications
+--------+
    ^
    |(1)
    v
+--------+   (2)
|  CORBA | <----> KDE/GNOME applications
| Service|
+--------+

Where (1) Is more or less the current NetMgr interface,
(2) is an IDL interface and
(3) is a way to fire up a connection

In a more desktop centric approach you could go for:

+--------+   (1)   
| NetMgr | <----> Non-X applications
|        |
|  CORBA |   (2)
| Service| <----> KDE/GNOME applications
|        |
|        | <----> PPP-dialer
+--------+   (3)
    
With of course the restriction that you can't dial out if
you don't have the desktop up and running.

If we have (1) and (2) standardized, everyhting is defined
for the applications.

The rest what we need is a way to specify what to use for
(3). E.g. whether to use ppp-on or kppp or something else.
