This minor technical difficulties could easily be avoided, they not at all a problem inside the CDN network, once your past the gatekeepers just look at twitch, it's a piece of cake to make it work even though the engineers will disagree.

The only technical limitation they had to bypass, was every little ISP being it's own little bridge troll about it and the CDN sidestep this entirely by running a whole parrallel network.

And now, there's all that CDN sunk cost making sure we'll never EVER have working multicast on the internet, and they'll have all the make believe excuses to pretend we can't ,even though, it's basically the same as unicast routing with extra steps....
