there's probably some extra bandwidth usage but it's using Data Channels, not streaming video. i'd love to know what a single character footprints is in ssh & in webrtc data-channels. evidently ssh is not actually that great[1]! webrtc might perhaps do better!! it is sctp/data-gram based! (personally i hope webtransport/quic eventually replaces this kinda odd/big stack)

once one starts doing Terminal User Interface programs or something is streaming to the screen, i expect potential differences to get less noticeable. hoping that packets get bigger. but definitely would like to see real evidence that packets get bigger, buffered, not just more numerous.
