Object Persistence Using a File System

[Chris Spencer]

Before I get too carried away with something that's probably 
unnecessary, please allow me to throw around some ideas. I've been 
looking for a method of transparent, scalable, and human-readable object 
persistence, and I've tried the standard lib's Shelve, Zope's ZODB, 
Divmod's Axiom, and others. However, while they're all useful, none 
satisfies all my criteria. So I started writing some toy code of my own: 
http://paste.plone.org/5227

All my code currently does is transparently keep track of object changes 
without requiring any special coding on part of the user, and a function 
to convert an object to a file system hierarchy of folders and files. 
Please, let me know what you think.

Thanks,
Chris
