Trivial to implement.  Basically, the file you want to look at is
gnome-pim/gncal/calendar.c, this one is the one who loads and parses
the calendar.

Instead of using a vCalendar file as the backing store, you can use a
database and each record can be a vEvent/vTodo (ie, in GnomeCal speak:
an iCalObj structure).

This might require some more magic.

You could go one step further: basically, the routine that populates a
day with events would just populate the range you have from the
database rather than populating it from the in-memory Calendar object.

The original implementation did support this, but it got dropped at
some point.

Note: we are going to be rewriting that in the short future (2-3
months from now).  Although we will be fully file-format compatible,
the GUI will be much better (that is the whole idea behind the
