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.

2. The negotiated wireless peripheral of claim 1 , further comprising:

an object that controls the non-area constrained user interface and maintains a point-to-point secure connection with the application so that all application data stored in the negotiated wireless peripheral is either in encrypted form or is in the protected memory area.

3. The negotiated wireless peripheral of claim 2 , wherein the object further comprises:

a program module that prevents other programs from accessing the protected memory segment.

4. The negotiated wireless peripheral of claim 2 , wherein the object further comprises:

a program module that monitors access to the memory segment and reports to a unauthorized access to the protected memory segment.

5. For use in a mobile unit that communicates with a negotiated wireless peripheral (NWP) device, a method comprising:

establishing via a wireless local area network air interface a position-dependent ecommerce session with the NWP device and contracting for the use of at least one peripheral that supports enhanced user interface capabilities;

redirecting at least one input-output stream to the at least one peripheral supplied by the NWP device in order to allow an application program to deliver content using a non-area-constrained user interface;

establishing via a wireless wide area network connection an end-to-end secure client-server session between the mobile unit and a remote server that provides an application service; and

supplying a client-side and non-area constrained user interface to the user to allow the user to interact with the remote server using the at least one augmented peripheral.

6. The method of claim 5 , wherein the method further comprises:

passing a remote object to the NWP device, whereby the remote object performs cipher processing and memory protection processing in the NWP device; and

invoking an input and/or output method on a stub object that securely communicates commands and/or input/output data to the remote object.

7. For use in a mobile unit that uses a wireless wide area network (wWAN) air interface to communicate via a wide area network (WAN) with one or more remote servers and a wireless local area network (wLAN) air interface to contract with a negotiated wireless peripheral (NWP) device, a method comprising:

establishing via the wLAN air interface a position-dependent ecommerce session with the NWP device;

redirecting at least one input-output stream to at least one peripheral supplied by the NWP device in order to allow an application program to deliver content to a non-area-constrained user interface, whereby the at least one peripheral includes an input device;

establishing or redirecting a client-server packet stream via the wLAN and through the WAN to support an end-to-end secure session between the mobile unit and a selected remote server, whereby the mobile unit performs cipher processing using at least one security parameter from an end-to-end security association between the mobile unit and the selected remote server;

storing in the mobile unit at least one secure information record for secure transmission to with the remote server; and

securely passing the secure information record to the remote server without the need to type in the information stored in the secure information record into the input device supplied by the negotiated wireless peripheral.

8. The method of claim 7 , wherein the input device is a computer keyboard.

9. The method of claim 7 , wherein the method further comprises:

passing an object to the negotiated wireless peripheral device, whereby the object maintains a point-to-point secure connection with the application and controls the storage of input-output data into a protected memory segment in the negotiated wireless peripheral device to inhibit a rouge processes from intercepting information from the non-area constrained user interface.

10. The method of claim 7 , wherein the method further comprises:

passing a remote object to the negotiated wireless peripheral, whereby the remote object performs cipher processing and memory protection processing in the negotiated wireless peripheral; and

invoking an input and/or output method on a stub object that securely communicates commands and/or input/output data to the remote object.

11. For use in a mobile unit that uses a wireless wide area network (wWAN) air interface to communicate via a wide area network (WAN) with one or more remote servers and a wireless local area network (wLAN) air interface to contract with a negotiated wireless peripheral (NWP) device, a method comprising:

establishing via the wLAN air interface a position-dependent ecommerce session with the NWP device;

establishing or redirecting a client-server packet stream via the wLAN and through the WAN to support an end-to-end secure session between the mobile unit and a selected remote server, whereby the mobile unit performs cipher processing using at least one security parameter from an end-to-end security association between the mobile unit and the selected remote server; and

projecting a non-area constrained user interface image on a projection-display surface in order to supply a display area in support of a non-area constrained.

12. The method of claim 11 , wherein the method further comprises:

storing in the mobile unit at least one secure information record for secure transmission to the remote server; and

securely passing the secure information record to the remote server without the need to enter the information stored in the secure information record into an input peripheral supplied by the NWP device.

13. The method of claim 11 , wherein the projecting involves a scanned laser image.

14. The method of claim 11 , wherein the projecting involves an LCD-based optical projector.
