Will do, but as you could see, I am a bit slow with this. :/

My criticism boils down to:
   - adding a hidden folder semantic, will make things
     more complicated especially for other clients.
     Together with access control, this means less security.
   - We need to solve the reminder issue for other folders anyway,
     otherwise we never get over this Outlook limitation. As we need
     to solve this anyway on the connector side, this even might be
     less work in the end.

True. I think it might be feasable to implement reminders for 
other calendars based on the incidences-for annotation
(as described in the Kolab-Format document).

I guess that most PDAs will not know about several calendars and 
will disregard some options that Outlook(+connectors) and the KDE Kolab Client
can deal with. The only way to solve this in my opinion is to 
somehow establish a connection from the appointment saved
to the smaller device and the mapping of capabilities.
My personal folder appointment will be saved to the PDA only calendar,
but getting the category "personal folder", so that syncing it back will
put it in the right folder.

I agree that it is doable,
for the reasons above I think that doing it differently will be even 
more secure, because of a structure which is easier to understand
for users.
