Currently objects can evolve themselves in their __setstate__ method.
The pack operation doesn't really know much about objects and their
classes, just records and transactions.

Absolutly, this is a great idea.  Why think hard?

I can't immagine that either RH or Debian designed their packaging
system without considering the idea of other people needing to use a
similar tool.  Perhaps there is a library that can manipulate either
format that we can use that does all the hard work for us?
