Couchbase Lite (http://developer.couchbase.com/mobile/develop/guides/couchba...) does exactly this - except it's not an actual Couch instance, but rather an SQLite database, and a client that speaks the necessary Couch protocols for sync/replication. Not so insane, and (as far as I've seen so far..besides git!) the only tool that really handles sync well across platforms.

edit: Ah, CBL (and Datomic) are mentioned in part 3 of the article. All is well :)
