Google Sync

Issue Summary

Is there a way to sync a calendar with a Google Calendar. I've figured out how to import a Google iCal and create my own event nodes. I've also figured how to create an iCal feed from the Drupal site. However, Google Calendar won't let me add events to a subscribed calendar, basically creating a circular subscription.

I guess what I need is to create an event on the Drupal site and have it update the Google Calendar on submission. Is that even possible, or would I need to write my own connection to the Google Calendar API. If I need to write it, could you point me in the right direction as to which module/file to get started. I would be happy to help contribute to get this functional (if it isn't already).

thanks,

david
