There's KCalendarCore::CalStorage which allows users to write their own 
calendar data sources, which could be used as a plugin interface. Extending 
the library with a plugin infrastructure would also be OK IMO, but if we want 
to have a bunch of plugins to integrate between KCalendarCore and various 
backend-specific libraries (e.g. KGAPI, KDAV, Kolab, ...), we should create 
KCalendarAddons (or something like that), assuming there's actually any demand 
for this.

For Akonadi the way it works is that we create an instance of 
KCalendarCore::Calendar and directly populate it with entities loaded from 
Akonadi. We don't use the CalStorage interface for that as we don't need that 
kind of abstraction to integrate between KCalendarCore and Akonadi.

Regards,
Dan
