In vanilla cases it's backwards compatible. I try packag-izing almost 
everything I install. Sometimes it works, sometimes it doesn't.

In your example, rfc822 uses only builtins at the top level. It's 
main will import os. Would that work if os lived in org.python.core?

Though I really don't think we need to packagize the std distr, (if 
that happens, I would think it would be for a different reason).

The 2 main problems I run across in packagizing things are 
intra-package imports (where M.A.L's proposal for relative names in 
dotted imports might ease the pain) and Pickle / cPickle (where the 
ugliness of the workarounds has often made me drop back to marshal).
