It concerns me that replicating partners with a differing versions of
CouchDB or any dependencies (ie. minor version differences?) could generate
different rev hashes of identical content.  I am ignorant as to how
different versions would actually affect in-memory representations so I
don't know if this is actually a concern or more like a footnoted
possibility.  Does this strike anybody else as potentially bad?
