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.
