The OP is talking about IP cameras that broadcast the video stream over
rtsp or similar protocols. All the IP cameras I've used have had no
problems streaming to several clients at the same time.
ZM can also use cameras that use v4l2 interface that use for example
/dev/video0 and you are probably right they can't be shared in a same
way although ZM does make the live stream available to any clients and
that is what mythzmserver uses to get the live video for those streams
although it is usually restricted to 10 or so frames per second rather
that 25/30 the cameras typically capture at.
