I not sure of anything.  :-)  Using calendars for database input, 
though, seems quite convoluted.  If I had to do that for some reason, I 
wouldn't set out to write CalDAV server in ObjC.  I would instead use an 
existing server and just find a hook to run ObjC code (or any language, 
really) when changes are made to calendars/events.

True enough.  Keep in mind, too, that whatever way is chosen, input from 
the calendar still requires parsing the iCalendar format and/or writing 
to an API that has done the parsing (e.g., Apple's EventKit).  It's not 
particularly complicated, but it is non-standard enough that it'll 
likely require more work than just using a common RESTful API using XML 
or JSON.
