Wonder if you have considered using a Sync Framework to manage the synchronization. If that interests you can take a look at the open source project, OpenMobster's Sync service. You can do the following sync operations

• two-way
• one-way client
• one-way device
• bootup

Besides that, all modifications are automatically tracked and synced with the Cloud. You can have your app offline when network connection is down.
