It used to be the case that after multiple vic instances started up,
they would each show all the video streams available at the address
they were subscribed to. After some time, the remote video streams
would drop off all but one of the vic instances; this would still leave
you with 3 vics - one with all remote streams + its own capture stream,
the other two with just their own capture streams. While still not
ideal, it was at least some mitigation of the problem you describe.
Although I say "used to be the case", it may well still be the case.
However, it takes some time to settle into that mode; ultimately we
found it unsatisfactory and now use single machine nodes only for
desktop/laptop (single camera) nodes, never room (multi camera) nodes.
Our recommended room style node consists of two linux machines i.e. a
video capture machine with 3 or 4 video producers and a display machine
with audio and a single video consumer. A nice addition is a third
machine, running as a separate node for doing presentations etc. We use
Linux on this machine, but Windows works too. Having a separate
presentation machine means that the presenter and operater don't have
to fight over who uses the keyboard & mouse.
