But there are some important issues: 1- We need to be able to open a 200MB log file with a snappy enough performance to be usable (including with a bit of font-locking). Most Web redisplay engines are not optimized for that case at all and many would tend to become completely unusable. So if we want to use a web engine, we may still need some intermediate layer that feeds only part of the buffer to the underlying rendering engine. 2- It needs to support all the features that we currently support. Most engines provide *different* features from the ones we have, rather than just strictly more. 3- I plan for Emacs to still be around in 2050, but based on past experience I suspect that all the current Web engines will have been replaced before 2050. So I think we need to see a Web engine as just another "backend display", just like currently have X11, Gtk, NS, w32, and tty backends. :-( Stefan
