Let's say you send a link to someone on an iOS device -- we can prompt them to install a native app, then as soon as they open the app, with no login, your call starts.

Apple actually is refusing to add WebRTC to Safari, because if you have good HTML5 support and WebRTC, you can do much more outside of a native app, which hurts their ability to control the app ecosystem, and helps developers ship to Android and iOS on the same day. I hope this changes, but right now it doesn't seem promising.
