Please, let's investigate that a bit more. If I understand you right,
KCalCore needs to prepare data differently for the storage if it uses
mkcal as storage - that sounds wrong to me conceptually, although I see
how that might be the most efficient way of doing it once you know that
kcalcore/mkcal are always used in that combination.

Of course, the big elephant in the room is the architecture decision to
use EDS for calendar storage again in MeeGo. I am hoping to keep
KCalCore as the main API for Qt based apps, even if EDS becomes the main
storage. This could be done by implementing a storage backend which
talks to EDS.

One advantage of such a change (if done properly) might become that
change notifications for individual events work again, instead of the
coarse "database has changed" that we currently get from mkcal.

I understand that we loose one major advantage of mkcal and possibly its
raison d'être (partial loading of data), but I am not sure how relevant
that is in practice. We had problems getting that to work reliably for a
while (https://bugs.meego.com/show_bug.cgi?id=6061#c5) and/or haven't
figured out how to use it properly (which events need to be loaded to
get a correct report about everything falling into a time range?).
