Can you give an example how that would wor for start/enddate ? I didn't 
find something in IMAP4 SEARCH which allows to query for "larger" or 
"smaller" headers (eg "x-kolab-startdate > 20030404") ?

The only thing I can see is "HEADER" or "TEXT" which only search for 
substrings and are (apparently?) unsuitable for range queries like 
"search apts from 2003-03-12 to 2003-03-19").
Maybe you have some smart idea on how to use them ? :-)

In my understanding in the current Kolab design the client is 
responsible for basically all processing (freebusy excluded ?), Kolab 
is just a generic store.

A lot of clients can show vcards or icals using a "plugin" 
architecture, if the message inside of the calendar folder will mark it 
using the correct MIME type, non-calendaring clients will be able to 
show some information nevertheless.
IMHO that's a nice aspect of the Kolab design.
