Well, we certainly don't do this. We do re-use outgoing connections that
have the same IP for dialback authority, though. I know older jabberd's
used to do this, but with XMPP v1.0 streams I believe you're not allowed
to open multiple streams on the same TCP socket. I would love to know if
anybody is opening multiple streams on the same socket as we'd have to
patch the server. ;)
