I didn't have any problems streaming to/from the broker, but I have to evaluate
at which point it breaks. I'll share these numbers with ffmpeg-devel.

Overall the idea is that you have a central broker that deals with these short
messages but also the high rate streams. You don't have to run a separate video
server and everything is logged at one place.
