Can you explain in more detail what you mean? Are there constraints on what the objects can be? If you have two objects: a = None b = (1, 2, "hello world", []) how would you describe the diff between a and b? If a and b are both numbers, the diff between them is just a-b, but this itself is a number and so transmitting it takes exactly as much memory as just sending b. Obviously if a and b are strings, the problem becomes trivial (just transmitted the string diff, which is a solved problem). > I was wondering if there > was/is any other research or development in this area?

The source code for pickle is available. See the pickle.py and pickletools.py files in your Python installation.
