Punakea is a little app trying to help you cope with the day-to-day struggle of managing your files. Designed to complement Spotlight, it allows you to tag your files and bookmarks, freeing you of the strict hierarchy of the Finder's folder structure.
There are at least two possible paths to get the information into Google: export from org mode to .ics; upload .ics to a public web server giving it a hidden/secret name; tell Google to import this .ics file use googlecl to import event when you create them into Google calendar (update entries won't be reflected in Google).
