-I've been using Cyrus-IMSP on my production srever in the past as a backend for the Horde Framework.It can, as the snippet states, primarily be used to store contact data, e. g. for shared and/or personal address books. Some applications can store user-specific configuration data in IMSP as well.There are just three problems with it:1. IMSP itself is obsolete since LDAP. Anything that can be done with IMSP can be done better in LDAP.2. (Cyrus-)IMSP never worked reliably and consistently for me.3.  Few applications  is an understatement. I've tried hard to find another use for IMSP besides Horde   and failed.I've long abandoned IMSP for those three reasons. I'd say: Perform the last rites!
