For me, the driving force is that most of the groupware products (Kolab, etc.) require it.  It appears that the shared folders in Cyrus, is what Cyrus does better than most of the other IMAP servers.  I could never get courier's shared folders to work consistently with all the users.  I sure hope it works better in Cyrus.  On the other hand, I personally like the Maildir's of courier rather than Cyrus and courier has been very reliable with many concurrent users and large email accounts.
