I dabbled a bit with recoding/encoding videos in the past: 40mbps is basically blu-ray quality (1080p/4k depending on content), and it's being used to stream a mostly-static background with some text scrolling in front of it.

A 3-minute chat with Claude suggests 30FPS should be plenty (perhaps minor cursor lag can be noticed if it's drawn), with a GOP of 2s (60 frames) for fast recovery, VBR 1mbps average with a max bitrate at 1.2mbps for crappy connections, and bframes to minimize bandwidth usage (because we have hw encoding).

The crappiest of internet cafes should still be able to guarantee 1.2mbps (150kb/s). If they can do 5-10FPS with 150kb frames, they have 6-12mbps available. Worst case GOP can be reduced to 15 frames, so that there's 2x I-frames every second, and the latency is 500ms tops.
