The Python web browrer stuff has a pointer to
http://developer.kde.org/documentation/other/kfmclient.html for info
on the Konquerer remote-control interface and uses

    def _remote(self, action):
        cmd = "kfmclient %s >/dev/null 2>&1" % action
        rc = os.system(cmd)
        if rc:
            import time
            if self.basename == "konqueror":
                os.system(self.name + " --silent &")
            else:
                os.system(self.name + " -d &")
            time.sleep(PROCESS_CREATION_DELAY)
            rc = os.system(cmd)
        return not rc

in case anyone wants to look into supporting Konqueror.
