Dave, flexcache will be a new feature in Riak 2.0. There are some subscribers to this mailing list that like to download and try things early. I was directing those subscribers to the GitHub branch that contains the work-in-progress code.
flexcache is a new method for sizing / accounting the memory used by leveldb. It replaces the current method completely. flexcache is therefore not an option, but an upgrade to the existing logic.
