Abstract: In one embodiment, a method includes determining when a relay arrangement is available to pair with an endpoint. The relay arrangement is arranged to wirelessly communicate with the endpoint and to communicate over a wired network. The method also includes authenticating the endpoint with respect to the relay arrangement when the relay arrangement is available to pair with the endpoint, and pairing the endpoint with the relay arrangement if the endpoint is authenticated with respect to the relay arrangement. Pairing the endpoint with the relay arrangement includes the endpoint and the relay arrangement engaging in wireless communications, as well as the relay arrangement engaging in wired communications over the wired network.

Abstract: In one embodiment, a system comprises a processor to maintain a skills database including different skill tags, each skill tag having an associated description, and a plurality of different subjects, each of the subjects being associated with a person, receive an endorsement for a first one of the subjects from a second one of the subjects endorsing a first one of the skill tags of the first subject, create a link linking the first subject with the first skill tag in the skills database, and based on receiving the endorsement, assign, in the skills database, a first expertise level to the first skill tag of the first subject, the first expertise level being dependent at least on one of the skill tags of the second subject and on a second expertise level assigned to the one skill tag of the second subject. Related apparatus and methods are also described.
