Is there a way to sync two sqlite3 databases?

I'm leaning toward using CouchDB, but short of that is there开发者_JAVA技巧 a way to sync two sqlite3 databases that have the same schema? I can try to use UID primary keys instead of auto-incremented ones, but I don't know the next steps if there are any.

that or RSync should get what you need.
