This is also something I would be interested in.
For all the non-German speaking people, Google Calendar Integration so that all events show up in realtime in a public Google Calendar, maybe with a link to the booking page for each event.
I could see this work both ways, not just from Matukio to gCalenar, where you can create events from Google Calendar (like your phone) and have those be unpublished in Matukio until you add other information, such as price, attendees, etc.
Yves, what do you think is the ETA on a feature like this, considering that this was posted a year and 9 months ago?
