But why does a client like kmail not need the administration user (in case of 
the iMAP annotations, I assume that kmail supports IMAP annotations on shared

Okay, clear.

Does this really make a difference in case the imap folder resides on the same 
system as the webserver?  I believe that this can be added later to horde, 
after the other points described above by Jan have been solved.
Dimap is probably very usefull in case the imap server is a different one and 
the user uses the agenda groupware functionality.

What about scalability?  Is it easy to add just another horde server, or 
should I say slave?  So, there should actually be 1 horde master and many 
replicated slaves (like ldap indeed).
