Back to Mosh: If it supports scrolling, how does that work? Is there also a prediction engine like in Mosh? What about ncurses apps? I skimmed briefly through the "how it works" page now, and it seems it also uses TCP instead of UDP. Shouldn't UDP be a better protocol for such a tool (also, that's what Mosh uses)? That page also does not say anything about how the prediction works (which is important in Mosh for the low latency), or whether it even does that (or how else could it have low latency)?
