An indication to share a content item associated with a residential cache appliance and a first social networking account is received. A network address of the residential cache appliance is associated with the content item. A cache map of available residential cache appliances is maintained to implement a distributed cache store. For one or more of the available residential cache appliances, the cache map identifies at least an associated social networking account, an associated network address, associated cache appliance stored content items, and an associated setting. From a requester device associated with a second social networking account, a request for the content item is received. In response to the request, based at least in part on the cache map, the requester device is directed to the residential cache appliance to obtain at least a portion of the content item.
