I have been surprised at the relative lack of interest from developers about first class syncing support, when mobile blew up I expected a flurry if libraries and tools that I could use to have my app work offline and sync data wherever I am.
Sometime last year I gave up waiting and started working on PouchDB (http://pouchdb.com/), its based on CouchDB's syncing model (and syncs with CouchDB) and works anywhere that Javascript runs (the browser + node), there is an iOS / OSX equivalent (https://github.com/couchbaselabs/TouchDB-iOS).
PouchDB isnt quite ready for production but its getting close, I would love any feedback on it, although I expect most people commenting on this would be more interested in TouchDB
