Philip, automatic synching of Neo4j is not at the moment one of the out-of-the-box features. Probably the easiest way is to define some form of messaging format, like JSON, XMPP or binary, and send things forth and back as you like. For your application, that might mean you need a messaging bus to send your clients changes to.
On the low level side, probably the online backup code might be of interest for you, as you can see what version the current neo4j store is at and pull out incremental transaction logs that give you the diff between two neo4j stores. We have not mad that a public API, but if you are willing to dig a bit, there might be interesting stuff for you in there?
