Hi Jeffrey,

Can Jason and others get around this problem for now by:

1. Subscribing to their Google Calendar with Chandler Desktop.
2. Exporting it from Chandler as an .ics file.
3. Deleting the Google Calendar subscriptiong from Chandler Desktop.
4. Re-importing their Google Calendar from the .ics file.

(If this works, I will write it up for the import/export FAQ page.)

Seems like the limitation here is that people can't get calendar data  
out of Google Cal as an independent (as in not bound by sharing  
access restrictions) .ics file.

That's separate from being able to subscribe to Google Calendars with  
Chandler Desktop and stay in sync, aka read-write sharing. If you  
want Chandler to stay in sync with your Google Calendar, allowing  
Chandler users to make local edits to read-only shares won't solve  
that problem.
