From the features section:
> Isolated streaming sessions: Each stream runs in its own compositor, completely separate from your desktop environment.
So yes, a compositor per session. I love the idea of a gaming box that can host multiple instances; that would be very very good.
Thank you I can see why it only works on linux. I can see this being successful with the SteamOS variants. Would this be a simpler way to share a gaming box across two different clients simultaneously? Like if my kids only played lightweight titles.
