Along these same lines, there seems to be no way to have multiple

No...
SRV records allow to independent XMPP services to run on the same IP
address, by specifying the port to use. Although almost every XMPP
s2s service operates on port 5269, and most operate on a host named
by the domain, this isn't actually required.
So although connecting to jabber.org:5269 will give you the
jabber.org XMPP s2s service, you're meant to find the host and port
to connect to via a SRV lookup of _xmpp-server._tcp.jabber.org, which
will tell you what to connect to. There's similar stuff for clients,
too.
And since XMPP clients (whether s2s clients or c2s clients) say which
service they require in the stream header itself, you can run
multiple domains off the same port (typically within the same
server). Most people do it this way, in fact.
So in fact, yes, you can have multiple XMPP services and servers
running on the same physical host.
