IMSP and ACAP and php3 and php4 for horde-imp

o LDAP is good for the white-pages of an organization; and, IMSP was designed to be more user addressbook oriented. o IMSP is in php3, but it is absent from php4. o IMSP has been superceded by ACAP .. which isn't in either php3 nor php4. o Turba for horde-imp addressbook is beginning with LDAP; and, eventually, I presume the other phplib abstraction containers. o I noticed CMU has a new ACAPD working with Bell's SML .. and the older C implementation is still around. o Might horde-imp find ACAP a suitable bottom-up addressbook and preferences container without the heavy LDAP top-down way? o Anyone know if ACAP will be added as a php3 function or php4 ext? o If added to phpN, might it be added to phplib?
