Right now, I'm in the heavy part of development for my new game, Farewell to Fear (http://www.kickstarter.com/projects/machineage/farewell-to-fear-a-progressive-post-fantasy-rpg) As a stretch goal, I've offered to redo the system as an Apocalypse World hack, in addition to the rules included in the game. So I'm not immediately working on it (particularly since we have yet to hit that goal level), but I'd be interested in getting some feedback when that time comes.
