I didn't even get into the webcam broadcaster software development aspects.
Any software developed for broadcasting in 4K would most likely be new, have to use raw sockets and be non Flash. It is not that Flash RTMP could not be used -- the problem is that browser support of Flash has a very limited shelf live today.
So, any new 4K broadcaster would probably have to be developed using WebRTC technology and that is only working 1:1 (peer2peer) currently -- we have a beta site currently but not doing 4K AFIK (today).

Canned product =Yes
Live broadcasting = No
Tell me when you get live television broadcasts like sports events (e.g.; football games) broadcast in 4K. The advertising money is there but the live broadcast technology is not there yet
