Technologies are generally presented for a relay forwarding system combining a data efficiency of soft forwarding that increases generalized signal-to-noise ratio with the ability to use hybrid-automatic repeat requests substantially high throughput levels may be maintained by using repair instead of packet re-requests. The method includes modifying behavior of the application on the client device through negotiation between the at least two resident entities according to pre-defined rules; and rendering the application on the client device based on the pre-defined rules using at least one of the resident client entities. A set of songs is then randomly selected from those songs that were actually played, e. Alternative embodiments of the securing mechanism include a key-and-keyhole combination; an interference fit facilitated by a chamfer or by one or more lobes or by shaped surfaces of the fastener body and of the load indicator; one or more tack welded interconnections; and an adhesive patch. In a further aspect of the present invention, the card or cards are able to communicate with the host in more than one protocol.
