LiveKit: multi-participant robotics beyond 1:1 connections

LiveKit is extending its SFU architecture beyond single peer-to-peer links so robot deployments can run multi-participant sessions, where a Room lets each camera, model, operator, or service join as its own participant. LiveKit describes three architectures: human-in-the-loop data recording with robot, policy, operator, and recorder in one session; VLM-guided skill orchestration where a vision-language model selects skills at roughly 1 Hz while separate policy participants control the robot at tens of hertz; and policy escalation, where a reward model at 30 Hz or higher flags stuck or unsafe states and the robot revokes authority from the specialist policy.
