Do you think it could be a good idea/useful thing? RTSP looks rather complex, wouldn't it be better/simpler to use a proxy? We have TPROXY so we can intercept udp and tcp connections; we have ctnetlink so the proxy could even inject expectations to keep the real data in the kernel forwarding plane.
