All the kolab data is already stored in imap.
Most of the horde preferencies are instead stored in the LDAP user profile.
This only other data that would completely remove the needs of SQL db
depend on the availability of "ldap datatree" driver which is estimated
a few days to be implemented.
In such way all the "kolab" data will continue to be stored in IMAP and
only the horde preferencies will be available trough LDAP directory
without the need of SQL DB.

And, if by design we doesn't want to store any preferencies by using
horde ldap schema, i don't think that would be so complex to create a
"datatree" and "preferencies" driver for horde that use as a backend an
imap folder. Perhaps 7-14 days?

Also this approach could be changed easily with few days work by using
the horde framework to adapt certain functionalities of Kolab driver of
various horde applications.

By using the previously described fix horde is "the" candidate for a
webclient interface, obviously imho.


A single google summer of code initiative would make horde a serious and
stable web client for Kolab imho.
