This is all French to me. Hopefully when it's ready, there will be a layman's version (assuming a layman would be capable of participating).

All I know is that I value steem-engine, and hope it continues to be available to desktop PC users (not just smart devices). I also hope the cost to make trades remains zero. I don't think the 1% fee to move funds on or off is too high, but if there's going to be a fee on every other little click, the free market will produce a competitor that doesn't do so.
