Well a bit of both, but the tunnel itself will carry pre-mixed sound.

e.g. setup is this:


[Local App 1] > +----------+
                | Local PA |  >   Tunnel    > +-----------+
[Local App 2] > +----------+                  | Remote PA |
                             [Remote App 1] > +-----------+


So Local App 1 & 2 will be mixed and passed out through the tunnel, then
the result will be mixed with Remote App 1 and ultimately output as
appropriate.
