Don't be too sure. The chrome part of the name may be because there is a browser in it.
Ah, good point. Makes app upgrades easy too. It's amazing what
you can get in a SoC these days...

Are you asking about content handoff (aka casting) or screen mirroring? They operate very differently.
DIAL is used for content handoff.
I'm talking about casting, but really both could use to be standardized. I looked over that document (i could only see the first 7 pages for some reason), and that kind of the way that Chromecast behaves but not exactly. Chomecast doesn't launch specific apps itself, it just fetches the media. I saw a vague reference to a token which I'm guessing is some sort of bearer token but didn't see how that works.
The larger issue is that this entire area is a mess with tons of opacity and lack of standardization. I can't, for example, use Firefox to drive Chromecast.

The DIAL protocol, used by Chromecast, is at least publicly documented: DIAL-2ndScreenProtocol-2.2.1.pdf (google.com)I've seen this before, and I'm pretty sure that it's not the whole story. Or maybe it's something more recent?

If we built such a thing would they come? It's extremely frustrating
that Apple, Google and Amazon all have different proprietary protocols
to cast media from your phone or laptop to a tv or whatever. they all
have interoperability problems because their petty business fueds, and
for users it is a complete nightmare to try to figure out what is going
wrong which happens way too often. Worst of all, is that since it's
proprietary we have no clue what is happening under the hood and
especially what is going on the security front. For example, if I were
to cast at a public venue would I potentially be opening myself up to
some sort of attack? Nobody but them knows and they aren't telling.
