This essay does not describe an existing computer program, just one that should exist. This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. I have no source, object, specifications, file layouts or anything else useful to implementing this project.

This project outline is not like the artificial tidy problems you are spoon-fed in school, when all the facts you need are included, nothing extraneous is mentioned, the answer is fully specified, along with hints to nudge you toward a single expected canonical solution. This project is much more like the real world of messy problems where it is up to you to fully the define the end point, or a series of ever more difficult versions of this project, and research the information yourself to solve them.

Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; or give you any additional materials. I have too many other projects of my own.

Though I am a programmer, I don’t do people’s homework for them. That just robs them of an education.

You have my full permission to implement this project in any way you please and to keep all the profits from your endeavor.

Please do not email me about this project without reading the disclaimer above.

This is JNI project that is more difficult than it sounds. Every Ethernet card has a 48 bit globally unique identifier called the MAC (Media Access Control). This gives you a unique id for a computer. The catches:

Your task is to research the Byzantine way you access the MAC in Windows, and write some C/C++ code to fetch it. Then write some JNI glue to make the MAC available from Java to signed Applets or unsigned applications.

The notes in the MAC entry may help.
