It's not always that simple, there's a lot of gateway issues we need
to take care of too. If I have a jabber server on IPv4 only,
and your XMPP SRV records has IPv6 only, I need a configuration for
redirecting the jabber messages to an IPv4 to IPv6
gateway. There are application level issues to handle migration here,
not only socket and DNS issues.
