The basis for that feature is there already (in Horde 3). The user
administration interfaces allows to clean all user data or to remove the
user data when deleting a user. The problem is, that not all backends
support this API yet. Actually only the preference backend is currently
supported.
It would be great if someone could write the missing api methods for the
remaining backends and applications.

You should use the vinfo hook for that purpose, it alters user names used
internally in Horde, to avoid name clashing if multiple users with the same
name can login to the same Horde server.
