This task can be broken in subtasks if we think that's necessary.

• Send update

When a sync message is ready to be sent, and the system allows for it to be sent (network available, not in blackout window from exponential backoff, etc) then sync message should be sent. This being done automatically should be the default, but the developer can override this behavior.

• Receive Update

When a client updates it data and successfully syncs to the remote server, the remote server will notify all of the relevant clients. The client must automatically and without user intervention receive this update and either act on it or store it for later processing.
