1. A method for maintaining communication over first and second disjoint networks between at least first and second computing devices, the second computing device comprising a mobile computing device, the method comprising:

  • using a first network identifier to identify the first computing device, communicating over a first network between the first computing device and said second, mobile computing device;

    authenticating the second, mobile computing device for authorization to communicate with the first computing device over the second network before sending a further network identifier to the second, mobile computing device over the first network;

    sending, to the second, mobile computing device over the first network, at least one further network identifier for use in at least in part identifying the first computing device on at least a second network disjoint from the first network, said at least one further network identifier being at least in part different from said first network identifier; and

    using the at least one further network identifier to identify the first computing device, communicating between the first and second computing devices over the second network, thereby allowing communications between the first and second computing devices to continue even though said network identifier changes.
