Purpose:
The patent relates generally to hybrid networks and, more particularly, to a network framework for facilitating interface roaming. User interface roaming is defined as moving from one interface (input and output device) to another while either maintaining application status and continuing from where the previous device left off (even if interface capabilities change), or changing application status to use a new application based on the new interface client's capabilities.

Plain-Language Scope:
A system, method and article of manufacture are provided for utilizing an interface client in an interface roaming network. An interface client submits information about itself to a nearby wireless link, then receives and displays content on a display. The interface client may first receive a signal from the wireless link—possibly in response to its own prior signal—which may identify a user of the wireless link. Submitted information may cover client capabilities, display capabilities, input devices, and location. Content may come from an infrastructure server, either via the wireless link or via the interface client's own connection. Content may be formatted based on the submitted information. The wireless link may act as a gateway; the framework supports various modes, including no external interface client, no infrastructure connection, and interface clients with direct server connections.

What the excerpt does not establish:
The excerpt is incomplete—it truncates mid-sentence in the FIG. 1 description and omits the claims, detailed description, and prior-art references. It therefore does not establish the specific claim scope, the full written description, or the prior art considered. The excerpt also does not detail the nature of the referenced reassignments (noted only as dates), and no legal conclusions about validity, enforceability, or ownership are drawn.
