What if there are multiple ways to connect to the Internet? Somehow the
notion of a "profile" would be nice where a different connection would be
used depending whether you are at home (LAN, DSL etc.) or travelling (cell
phone etc).

If you look at the signals of KpppIface you'll notice 4 different once:

 void aboutToConnect();
 void connected();
 void aboutToDisconnect();
 void disconnected();

So it might be useful to have both pre and post signals for triggering
certain actions. Whether that should be crammed into the enum or in
additional signals I don't know.

Or is this the one you meant to (partially) achieve the purpose depicted
above?

Thanks for getting this going,

Harri.
