I'm working on a new independent LaTeX engine written in Rust and no C dependencies at all. You can see it working at https://news.ycombinator.com/item?id=49689856

I've experimented with a few ways of making the editing realtime and I'm getting in the 10 millisecond ballpark on some edits, but I want to work backwards from the light speed path to see what it takes (besides a lot of time).
