What do you mean by "in the future" ? How do you plan to work around the 
problem that you cannot identify the type of the folder ?
Do you plan to make any folder available for any folder type and filter 
on the content type of the message ?

I thought so.

This is because you have no shared calendar folders but only a single 
private folder which is stored on the server, all scheduling is done by 
copying all information for any user ? (where copying is implemented by 
sending mails which are automatically processed ?)
What happens if two people move/annotate/edit the same meeting record at 
the same time ?

If you have a read/write shared folder you have "typical database 
problems", don't you ? ;-) [actually not database problems, but 
multiuser system problems]

BTW: is the Kroupware address book stored in LDAP or in IMAP ?
