Here is a list of streamers playing QuakeWorld, maybe useful for some:

Taken from http://www.quakeworld.nu/forum/topic/6560/streamers-needed#103383

Better fasten your seat belts on some streams (carapace_, rikoll) because you may get FOV-raped:)

I have no idea how to get those listed in the ESR stream section, anyone knows/wants to do it?
