→Shared Calendar Functionality
----
It is possible (on a small scale anyway) to share a group Lightning calendar on a windows SMB or CIFS mapped drive instead of implementing a proper DAV type service. Be advised, this is an egregious kludge and I'm sure a race condition between two users writing to the same .ics file could easily occur in practice as this is not officially supported functionality and there doesn't appear to be any locking mechanism implemented in Lightning -- wouldn't trust filesystem locks either, however, in testing, intentionally racing 2 instances of Lightning (creating a new event) threw a "calendar unavailablechanged remotely, please reload and reapply" error on one instance when writing to a shared .ics hosted on a samba 3.3.8. This error might also toggle a client into read-only mode, so some concurrency checks seem to be implemented. Did not cause any data corruption in a few test collisions.
As of Lightning ver 1.0b7, a user can create a new calendar, then right-click "export" it into an .ics file. The ics file can moved to a network share. Any user who can read the file can then "File/Open/Calendar File" to load it into Lightning. If the user has write access, they can update and add events to the calendar. You can set calendar properties to refresh once a minute (restart to take effect), or manually on demand, to propagate changes.
