How are you doing this?

A while ago I skimmed the documentation for a couple of CalDAV servers to try and figure out how I could self-host a shared calendar, but couldn't see an easy way to do this.

I've just done some more searching, and it seems there are two suggested ways to do this with Radicale:

* create a separate account for the shared calendar, and tell everyone who needs write access the password

* create the calendar in one use's directory, and add a symlink to it in the user directories for any other users who need write access.

Both of which seem like a bit of hack compared to bring able to explicitly state that a list of users have write access to a calendar in a config file or through a UI.
