Getting deeper and farther into trying to do Operational Transformation with Erlang wxStyledTextCtrl, aka. Scintilla and TextDelta. I end up doing almost no TextDelta or Operational Transformation in this one as I try to pin down whether I can reliably insert and delete text from the different editor sessions without causing endless loops of updates. Turns out that there is no great facility for handling that. We learn quite a bit.
