    Sure use something like a guid as the primary key in the table (to avoid conflicts when syncing).

    There are many strategies for syncing the data. One is to always write to the local database and have a background thread which syncs the records. The thread can he started by a button click. You can track a synced record in the local db by adding a column like a datetime column - just insert the current date/time when the record was sucessfully synced. The background thread will sync records that don't have the sync datetime column set.
