1. A negotiated wireless peripheral device comprising:

  • a short-range wireless transceiver operative to support a position-dependent ecommerce session with a mobile unit;

    a negotiation module coupled to the short-range wireless transceiver, the negotiation module operative to engage in a handshaking sequence with the mobile unit to establish the position-dependent ecommerce session;

    a WAN gateway module operative to couple a traffic stream generated in the mobile unit and received via the short-range wireless transceiver to a wireline WAN connection, so that the mobile unit may maintain an end-to-end secure connection though the negotiated wireless peripheral device with a remote server coupled to the WAN;

    a peripheral augmentation system operative to redirect one or more I/O streams to/from the mobile unit to a set of one or more peripheral devices that support a non-area constrained user interface to the user of the mobile; and

    one or more protected memory segments that are provided for exclusive use by one or more I/O processes that support the non-area constrained user interface.
