The Kune calendar can be imported in Google Calendar (Other calendars => add by URL => paste the address, e.g. http://kune.cc/ws/servlets/EventsServlet?token=kune.events.11 )
It properly adds the events, although there seems to be issues with the encoding (unicode, etc). In this case, the "ยท" of the event http://kune.cc/#!kune.events.11.5848 shows two "unrecognized character" symbols.
