Do any of you use Cloud9, Brackets, emacs + xhost, or some other tool/service? Do you recommend them? http://etherpad.wmflabs.org/pad/ is all very well and good but it doesn't support syntax highlighting.
FWIW there is a way to add in syntax highlighting, and I could probably create a new instance for that. There was also chatter on the Etherpad channel yesterday about writing plugins for compiling and running programs on the backend of the server.
Let me know if there's interest.
