OK Thanks, for the answer,

Forgive me my ignorance. I am an experienced Python developer, but I know 
nothing (or next to nothing) of dcop, interprocess communication with other 
kde applications and the like. However, I DO know that it is possible, and 
there are many different ways to achieve my goal.

PyKDE seems to be too much, because it uses Qt which is not necessary, as I am 
already using wxPython (gtk). pydcop is there, but I haven't got a clue how 
to use it, I have spent several hours Googling to get examples, but there 
seem to be no examples whatsoever.

Synchronisation with our own application. To be more specific: our application 
is a wxPython application using Postgresql. In the application actions are 
stored. Some of those actions require an appointment with someone else. If 
there is an appointment available for an action I want to show that 
appointment in a screen.

So I need to be able to identify a specific appointment made by the user, 
store that key in my database, and be able to retrieve the appointment 
information so that I can display the information of the appointment.

I found out that I can read/write to std.ics and by doing so can get the 
information that I need. There is a python module iCal with which I can read 
an iCal file, and interpret it. Probably I have to adapt iCal a bit to allow 
for an identification of a specific appointment, (UID in iCal).

Are there any objections in using this approach? It looks a lot simpler than 
using kitchensink / multisync.

I have looked at the howto for connecting korganiser to ms-exchange. It is 
very important for the users to be able to use the free/busy information when 
they are making appointments. In the howto, there is no description of what 
EXACTLY are the functions that are supported. I know it uses webdav, but I 
just don't know if that supports the all important free/busy functionality. 
Again it is probably lack of knowledge from my side about what webdav offers.

To use ms-exchange as a mailserver is obviously simple, using imap or pop.

OK, probably I'll do it differently, using Onidle in wxPython, and simply read 
std.ics file, which means that it should be always be up-to-date.

Yes, after rethinking the requirements thru once more, I probably don't need 
to do syncing in both ways, as the appointments can be entered in korganiser, 
and the application only needs to be able to retrieve the existing 
appointments, as I described above.

Once again I am not clear. What I want to achieve is that the user gets a 
warning when a room is already occupied, a beamer is in use etc. And that I 
have free / busy information about these resources.

OK I hope I have made things a bit clearer now.
