It should be, but it isn't, for two reasons: 1. Emacs highlighting support is minimal. Kludges are necessary to get Emacs to highlight a particular region of text, and these kludges usually require you to clear the current window for each new page, which means no screen update optimization. This will be a nightmare at low baud rates. 2. Emacs' window management code behaves strangely, at least to me. It is difficult to determine what the value of window-start is going to be at next redisplay, and you need to know this in order to do the highlighting kludge mentioned above.
