Cool! It'll be interesting to follow your work. I've been thinking, as well, about quorum and voting systems that might benefit from some structure. The primitives you've described are great for the "do N things one time each" case, but sometimes I (and the AI) want "do one thing N times: pick the best somehow". (I mean, you can express that with map/reduc over small integers or something, but still: different flavor.) You can even bring public choice theory into it.
