I know this feature isn't there, and it's probably not planned, but I loved it). Clearly, the feature is not needed by everyone. However, rival Goblin face pair quite samodvizheniya this topic.

Out of curiosity, I know of Parsec and Moonlight (which utilizes Geforce Experience). Are you aware of any other 3rd party tools for local network streaming?

Any software that can do streaming via network, will work locally.

Yes, but most solutions I have seen are more of a 'game as a service', where you stream the game from a 3rd party provider over the internet.

I haven't seem too many streaming products that are fast enough for gaming.

I've not tested this myself, but what's to prevent you from taking a GOG game, adding it to Steam as an external game and streaming from there?
