I've been mulling over the concept of a codec designed for streaming NES video. Stream the VRAM tiles and the RAM data needed to reconstruct the output locally, which could be done in a shader along with CRT simulation if desired. Very much a one-trick pony, but probably considerably less bandwidth-intensive than even the original resolution (320x224) under nearly any acceptable bitrate.
