Yes, but if we need authentication to make the transport secure, we need
to know that there is no man-in-the-middle. I guess TLS-SRP would work
perfect for you: the user provides a password with SRP and the peer
provides a certificate the user can check. Based on that the channel
will be secure.
If you only do SASL, you can not be sure that someone changes the data
after the SASL authentication. Maybe you don't need to if you trust the
XMPP servers involved.
