I sure did like the core<—>core communicating idea for multiple users of a single document. It seemed like an easy trap to imagine X11 as the f/e, b/e, plugins, async were talked about, but not “just” using a remote f/e to communicate w a remote core was sort of enlightening (having fell into the X11 trap as the talk was progressing). Question re: json communication though: is there a space for something like protocol buffers here, or is that a case of YAGNI, or simply ill-suited?
