Fun little exercise! Maybe you already solved it yourself,
but if not, here's a spoiler:

Create one tunnel sink per machine. Create one combined sink
per stream, each using all four tunnels.

Now each combined sink has four streams, each going to one
tunnel. That means 16 streams (plus the 4 mpd streams). By
muting these 16 streams as needed you have full control over
what goes where, without any drop-outs.
