I don't see why it would really be beneficial - People who want to connect with a remote Emacs session just use ssh + screen or tmux, which is stable and quick to set up. If you really want to implement Emacs-over-the-web, though, familiarity with these might help: distel - distributed elisp, via integration with Erlang (http://fresh.homeunix.net/~luke/distel/ http://fresh.homeunix.net/~luke/distel/) TRAMP - remote file editing (See e.g. http://www.emacswiki.org/emacs/TrampMode http://www.emacswiki.org/emacs/TrampMode) Also, there are decent web browsers for Emacs. I like emacs-w3m. (http://emacs-w3m.namazu.org/ http://emacs-w3m.namazu.org/)
