A ring binder mechanism is attached to the spine of a notebook by pressing prongs of pre-attached anchors into the spine material. Using a logical cut-through device between a pair of virtual routers designated respectively client and server, packet forwarding information from the server is imported into the client, which creates, allocates, and maintains a data structure for the imported information, which then resides on the client interfaces. Next, an energy beam is directed onto selected areas of the powder blend layer to thereby melt the alloying metal. In another embodiment, the entertainment system selectively renders a selected one among multiple received commercials.
