Or you can download it from RubyForge:

I would use KDE::System tray to add an icon with a menu to the kicker system
tray, here's an example:

require 'Korundum'

class MainWin < KDE::MainWindow
    slots 'slotQuitSelected()'
        
    def initialize(*args)
        super
        @exitFlag = false
        icons = KDE::IconLoader.new
        systray = KDE::SystemTray.new(self)
        systray.setPixmap(icons.loadIcon("stop", 0))
        connect(systray, SIGNAL("quitSelected()"), self,
                SLOT('slotQuitSelected()'))
        systray.show
    end

    def queryClose
        hide
        return @exitFlag
    end

    def slotQuitSelected
        @exitFlag = true
        $kapp.quit
    end
end

about = KDE::AboutData.new("systray", "A system tray", "0.1")
KDE::CmdLineArgs.init(ARGV, about)
app = KDE::Application.new

mainWindow = MainWin.new(nil, "main window")
mainWindow.show
app.exec

Then start a konsole instance with a DCOP call:

error = ""
pid = Qt::Integer.new
errcode = KDE::Application.startServiceByDesktopName("konsole", "", error,
"", pid)
dcopService = "konsole-" + pid.to_s

I'm not sure how you send an ssh login command to konsole though.
