The only options to share an event, or a team's calendar are to share with LinkedIn or Facebook. I would like to display my team's events in my own Thunderbird/Lightning calendar, or Google calendar. Having an iCalendar sharing option would provide this integration.
.ics files should be available for all events for a team, but also on a single event.
Eventually I would like to see CalDAV functionality, so that I can submit or edit events from my preferred calendar client app.
