The Python version would use pickle or cpickle to serialize the snapshot and
the command log. So this system would build upon Python's pickling
capability. By logging all mutators the system can recover from failure by
reloading the last snapshot and reapplying commands from the log. I'm also
hoping that combining this with Pyro (Python Remote Objects) would get one a
simple, scalable, robust, multi-user object persistence system. At least,
that's my goal in all this.

I guess that was implied. <wink>

Curiosity is good... as long as you aren't a cat. :-)
