SPICE smart streaming
summary
SPICE moves to whole-desktop H.264 streaming and implements a control loop that sends tagged metrics from clients to server, plus a recorder for live tweaks and a top-level build so experiments run end-to-end. Two algorithms are tested: a dumb one that sets host FPS to observed client FPS and a longer heuristic; surprisingly the dumb algorithm performs as well as the complex one. Smart streaming reduces bandwidth first to preserve FPS, recovers a client backlog in about one minute, and is promising but not yet merged.
