Is this support synchronization/off-line access (like good IMAP clients), or on-line access only, or import/export only? I'm looking to add something to our webmail site that synchronizes the Windows Address Book and other common mail client address books with our server address book. I can't find anything that supports this--the obvious choice would appear to be to use LDAP on the server, but I can't find any clients that support synchronization of LDAP with local address books.
