From what I understand, Salsify requires a unique connection for each device being served a stream. Therefore (like WebRTC) you can't cache frames in a CDN; and each viewer requires a connection to the origin. This gets a little expensive (which is one of the reasons why WebRTC isn't very common relative to HTTP streaming). Have you explored any kind of multicast or cache-friendly variation of Salsify?
