NiceDCV/AppStream with multiple viewers

Hey everyone,

I've got a customer who does interactive art installations, using mostly gaming engines (Unreal and Unity primarily). They have an ask for mutliple viewers to a NiceDCV stream, on the order of 3-5 viewers, not hundreds/thousands. I can't see an obvious way to have multiple clients attach with NiceDCV.

IVS is <3 seconds latency, but this will be too slow for them to be able to use it.

They currently use gamelift for server-side state for several workloads and would otherwise have multiple instances (on-prem/appstream/ec2+niceDCV) staying in sync via a gamelift server. But in this case avatar control is out-of-band and they have a single shared viewport across multiple sites instead, so it would be a waste of resources and we'd love to be able to avoid that.
