FIELD: information technology. ^ SUBSTANCE: wide-area network (WAN)-based service enables remote data access transactions between participating endpoints within a group of participating endpoints which includes at least one server and at least one portable electronic device. Each participating endpoint is configured for communication via one or more communication networks and stores the same or different data items on behalf of a user. The WAN-based service supports information about each participating endpoint and its network accessibility, and also supports one or more catalogues of available data items. The WAN-based service identifies a communication network available to both participating endpoints, and a direct or proxied communication session is established between the portable electronic device and the other participating endpoint via the communication network. Selected data items are downloaded, uploaded, opened or synchronised via the communication session. The use of digital rights and identity management techniques in combination with the WAN-based service is also described. ^ EFFECT: providing a network endpoint access to digital content deployed on other endpoints regardless of network settings. ^ 20 cl, 4 dwg |
