If you are interested in mobile JSON databases, we've been working on our network-enabled native databases for iOS, Android, C# and PhoneGap, since 2010. The library size is less than 500kb and we are compatible with the Apache CouchDB sync protocol. We also have a server side Sync Gateway that has fine grained access control, webhooks, etc. Did I mention everything is open source? There is a mini-hack here that will let you choose your platform and be up and running in ~20 minutes with what's basically the stem cell you're gonna be winning hackathons with now that you know. https://github.com/couchbaselabs/mini-hacks https://github.com/couchbaselabs/mini-hacks Ps we couldn't have done it without SQLite as we started out using that for our storage engine. Now we are moving to ForestDB because it's more like the data structures we present in our API.
