Piggybacking off this, is there a way to allow only certain channels. Unless i missed it, even on YouTube kids I only have the option to block...and to my horror one day I let my kids watch the Peppa Pig official channel and find out later through YouTube recommendations they were watching some grown man playing with Peppa Pig toys.
Also, my eldest is 6 and already knows you can get to YouTube via browser -__-
I was at FOSDEM that year but unfortunately missed your talk. Just watched the video of it and it was very well explained, taught me a thing or two about CDN's and SPOF's, thanks for that.
