I think P2P is still the way to go. Sure it’s not perfect, but it’s simpler and by it’s very nature doesn’t require the infrastructure we know will be a problem.

Plus, don’t forget screen sharing in discord isn’t very good as is (720p30) if you’re not a paid user.

Voice control of devices you have in home assistant is cool, but I don’t think I would recommend it to an average person who uses Google assistant. Sure it can turn the lights on and off if it’s aware of those entities, but this user is describing playing games, asking for media streams, podcasts, all things home assistant voice does not support (certainly not out of the box).
