Here's a ruby app that connects to kppp via dcop signals:

require 'Korundum'

class KpppMonitor < KDE::DCOPObject
    def initialize(*args)
        super
        connectDCOPSignal(nil, "KpppIface", 
                                      "connected()", "kpppConnect()", 
                                      false)
        connectDCOPSignal(nil, "KpppIface", 
                                      "disconnected()", "kpppDisconnect()", 
                                      false)
    end
 
    def kpppConnect()
        puts "kppp has connected"
    end
 
    def kpppDisconnect()
        puts "kppp has disconnected"
    end
end

class MainWindow < KDE::MainWindow
    def initialize(*args)
        super
        @kppp = KpppMonitor.new
    end
end

aboutData   = KDE::AboutData.new("kpppmonitor", "Kppp Monitor",
    "0.1", "Monitor kppp via signals", KDE::AboutData::License_GPL,
    "Richard Dale")
KDE::CmdLineArgs.init(ARGV, aboutData)

app = KDE::Application.new
mainWindow = MainWindow.new
mainWindow.show
app.exec
