Architecture:

(1) Session ----- NodeAgent ---\         /--- (1) Browser
                /               \       /
(2) Session ---/  NodeAgent ----- [Hub] ----- (2) Cmdline
                                /       \
(3) Session ----- NodeAgent ---/         \--- (3) Browser

GOAL:

• [DONE] control http client from server
• [DONE] switch between connected clients
• [DONE] stream client command output

Requirements:

• [DONE] HTTP(S) -> TCP
• [DONE] TCP -> RPC
• [DONE] TCP -> gRPC
• [DONE] gRPC <=> Websocket

Potential use cases:

• distcc agent (cpu/io intensive)
• anonymous proxy endpoint (io intensive)
• crypto mining worker (cpu intensive)
• ddos attack agent (generate SYN flood, ICMP, UDP, TCP traffic)
• distributed web scraper (cpu/io intensive)
• podman/buildah/skopeo build log streaming with dind (Docker in Docker)
