I have what I was hoping could be a shared family calendar set up on OwnCloud. I have no problem syncing it to Sunbird and my phone, but my spouse uses Google Calendar (ie. http://calendar.google.com) for everything and he can't subscribe to CalDav calendars, as far as I can tell.
I can get an ics feed out of OwnCloud by adding
?export to the CalDav URL, which is handy, but that produces a read-only feed.
Is there a straightforward (or convoluted) way for me to allow him read and edit a caldav calendar within Google Calendar?
