And many others, like clustering. migration . Implementing ( and easy
building ) of third party applications which to manipulate objects in
database. 
For example: Consider you have 2 GB IMAP folders in your inbox. Now
imagine that you start new client on new PC. I bet that pure SQL queries
to database will be far fast, that IMAP to index these objects.
Second - Get rid of disconnected IMAP ( IMHO this is the only thing that
stop me to use kolab)
