  Nice work, this layering feels saner to me.
  
  Regarding the request/result split for caching, while I agree that caching deltas is something worth pursuing (it was an enormous win on code.google.com!) it's also not something anyone has cared a ton about, and I could also see it living in the store layer directly.
