I have so far only looked at the talk.txt file, but this looks indeed interesting!
I think whether this approach of handling dialogs is useful or not is really depending on how much keywords the NPCs understand. As long as they only react to 1-4 words, I would prefer to handle the dialog with question lists, because otherwise, it would be really frustrating for the player to try around with dozends of words and not getting any reaction.
However, in case the NPCs react to several words and -even better - react to different combinations of words (this is appearantly also done in this demo), then I would like such a dialog very much.
