Object Diffs

[Croepha]

Hello Python list:

I am doing research into doing network based propagation of python
objects.  In order to maintain network efficiency. I wan't to just
send the differences of python objects, I was wondering if there
was/is any other research or development in this area? I was thinking
that I could look at how pickle works an implement a diff system
there, or I could actually create a pickle of the object and then use
difflib to compare the flattened text...

Ideas, or comments welcome

Thanks,
Dave Butler
