Many people seem interested in single machine nodes at the moment.
There are lots of good reasons to have such a setup (besides just being
able to say that you've done it). In particular, they're great for
desktop systems with a single USB camera, and also for laptops.
However, from a useability point of view, they're not ideal for
multiple camera nodes. There's an instance of vic (VideoProducer or
VideoService) for each of the video capture streams, say 3 in a typical
node. Thats probably OK for an experienced operater, but even then its
a bit inconvenient (and, at the very least, messy) having the
additional vic instances on the display machine. For a casual node
operater, its really confusing.
With a separate capture machine, the multiple vic capture instances are
tucked away on another machine with only a single VideoConsumer on the
display machine. Its a much neater solution. The more useable a system
is, the more its likely to be used.
