A developer built a full video conferencing app on S2, a service that treats append-only logs as a first-class cloud storage primitive. The key architectural insight: when streams are durable storage (not just transport), live viewing, recording, replay, and MP4 export all collapse into uniform stream reads — no separate recording pipeline or post-processing. A Go server handles media via AppendSession/ReadSession with 5ms batching windows; MP4 export pipes stream data directly into ffmpeg with no intermediate files.
