I test geo events and make Calendar. You can add New calendar to your Calendars. Now this calendar have 2 events. You can see events in GMaps by click and select in Where link Map You can see this calendar as HTML or XML You can see and use this with Feedburner
You can also insert into your Calendar events only. One or two.
I do not know all ways from this. It's see very interests.
