## Abstract

A client device is enabled to access content by generating a request to access content residing on a host. A rule set associated with a user is accessed that includes one or more rules configured to identify content responsive to a predicted interest of the user. The rule set is used to identify content selections from a library of content selections available on the host. A first address corresponding to a first content selection and a second address for a second content selection identifying are identified from among the identified content selections. The first content selection is accessed from among the identified content selections by establishing a connection to the host at the address identified for the first content selection. In response to receiving a change instruction to change a content selection being rendered, the second content selection is accessed from the identified content selections at the second address.
