The one or more recipient devices (e.g. 102a, 102b and 102c) and the data deliverer 104 may be located remotely from one another. In an embodiment, the data deliverer 104 is configured to perform a method 200 including steps 202, 204, 206 and 208. At step 202, the data deliverer 104 determines a schedule of data delivery.
