Abstract: A computer system allows two devices operated by two users from a plurality of trusted users to establish a direct peer to peer limited range wireless connection based on a social network connection between the users. The first client device associated with a first user receives a list of the plurality of trusted users from the computer system. The first client device receives a limited range signal broadcast by a second client device. The first client device determines that the second client device is associated with a second user from the plurality of trusted users based on the list and the limited range signal. Responsive to determining that the second client device is associated with the second user from the plurality of trusted users, the first client device establishes a direct peer to peer wireless connection. The first client device transmits content to the second client device via the peer to peer wireless connection.

Abstract: A computer system allows two devices operated by two users from a plurality of trusted users to establish a direct peer to peer wireless connection based on a social network connection. An online system uses social network connection information to determine trusted users for each of the client devices, and monitors the geographic locations of the client devices. Responsive to determining that the client devices are within a predetermined distance from each other and are trusted users for each other, the online system transmits connection information to the client devices, prompting the client devices to establish a direct peer to peer wireless connection through which content can be transmitted.

Abstract: Systems, methods, and non-transitory computer readable media are configured to evaluate, by a computing system associated with a user, a sharing policy associated with a media content item. It is determined whether provision of the media content item to a second computing system associated with a second user is permissible under the sharing policy. The media content item is transmitted to the second computing system in a peer to peer manner when the provision is permissible under the sharing policy.

Abstract: In one embodiment, one or more computer systems of a social-networking system access a notification to be delivered to an identified user. The one or more computer systems of a social-networking system access registration data maintained by the notification-providing system and associated with the user. The one or more computer systems of a social-networking system identifies, based on the registration data, an endpoint associated with the user to which the notification will be delivered, wherein the endpoint includes a particular application installed on a client system associated with the user. The one or more computer systems of a social-networking system causes the notification to be sent to the identified endpoint.
