Many XMPP server implementations tie in directly to LDAP databases, but
that's more of an implementation issue than a protocol issue.

Sharing of rosters is discussed somewhat here (not yet sure what your
requirements are):

See above (maybe).

It's on the way. :-)

We have TLS for channel encryption, I'm working to make that more
widespread (probably by having the Jabber Software Foundation, or an
initiative thereof, act as an intermediate certification authority for
the XMPP network).

We have SASL for authentication, that includes things like Kerberos in
many server implementations.

We don't have one agreed-upon method for end to end encryption. Previous
attempts have included OpenPGP and S/MIME. The focus now is a form of
opportunistic encryption that is similiar to off-the-record messaging
(OTR, perhaps familiar from Gaim), but that enables us to encrypt the
entire packet, not just the plain text message body:

Hope that helps. I'm looking forward to our discussion.
