5. The apparatus of claim 1, wherein the subset of functions of the smart meter comprises non-communication functions, wherein communication functions relate to communications between the smart meter and the AMI/AMR network.

6. The apparatus of claim 1, wherein the computer processor is coupled to and is configured to communicate with a gateway trust center.

7. A process comprising:

providing a computer processor to communicate with a smart meter in a home area network (HAN) and to communicate with an advanced metering infrastructure (AMI) and advanced meter reading (AMR) network; and

executing in the computer processor a subset of functions of the smart meter;

wherein the subset of functions of the smart meter comprises coordinating the HAN, storing HAN information, storing one or more security keys, authenticating devices for the HAN, associating devices in the HAN with the smart meter of the HAN, storing device profile information, handling software upgrades, and storing sensed data; and

wherein the computer processor is coupled to and is configured to communicate with a retail electric provider (REP), and wherein the REP comprises a second computer processor that is configured to execute a subset of functions of the smart meter in the HAN.

8. The process of claim 7, wherein providing the computer processor to communicate with a smart meter comprises configuring the smart meter to discover the computer processor and configuring the computer processor to discover the smart meter.

9. The process of claim 8, wherein the smart meter initiates an authentication and association with the computer processor.

10. The process of claim 7, wherein the computer processor downloads firmware to the smart meter, the firmware configured for operating the smart meter, and wherein the computer processor downloads utility configurations to the smart meter, the utility configuration comprising one or more of a security credential, a unique identifier, and a utility program enrollment information.

11. The process of claim 7, wherein the smart meter associates one or more devices in the HAN by transmitting client association and security information to the computer processor;

and wherein the computer processor authenticates the smart meter and the one or more devices using information from the AMI/AMR.

12. The process of claim 7, wherein the computer processor stores data in an AMI/AMR database such that the computer processor does not have to poll the smart meter.

13. The process of claim 7, wherein the smart meter and the computer processor transfer data and utility control information from the utility to the HAN and from the HAN to the utility.

14. A process comprising:

providing a first computer processor to communicate with a smart meter in a home area network (HAN) and to communicate with an advanced metering infrastructure (AMI) and advanced meter reading (AMR) network via an AMI/AMR link;

executing in the first computer processor a subset of functions of the smart meter; and

providing a second computer processor, wherein the second computer processor receives firmware from the first computer processor, the firmware configured for operating the second computer processor;

wherein the first computer processor is configured to download utility configurations to the second computer processor, the utility configurations comprising one or more of a security credential, a unique identifier, and utility program enrollment information;

wherein the subset of functions of the smart meter comprises coordinating the HAN, storing HAN information, storing one or more security keys, authenticating devices for the HAN, associating devices in the HAN with the smart meter of the HAN, storing device profile information, handling software upgrades, and storing sensed data; and
