John,

Could you please share a link to the materials of the discussion you've
mentioned, or may be place where the discussion takes place (if it's
online)? We're currently working on R&D project that involves prototype
implementation of regions, and I'm eager to see suggestions for replication
optimizations and possibly get some feedback about our approach.
