A gateway device is disclosed for deployment at user premises, which offers applications services similar to those of a server from the premises, albeit managed by a service management center via the network. For each application service, gateway programming provides application server communication with a client functionality of an endpoint device, for the respective service, communicated on top of network layer communications within the premises and through the wide area network. The application service logic in the gateway device also enforces authorization, authentication, configuration, or use of the service via the endpoint device. Management of the application service is responsive to communications with the service management center via the wide area network. A gateway device of this type, for example, may offer PC or TV type user interfaces. The gateway also may establish peer-to-peer communications with other similar devices.
