   Few days ago someone called Ty Sarna implemented CompressedStorage for
Zope (www.zope.org). (S)He took exactly this approach - compress pickled
data. As Zope database could be large, I think (s)he did consider this
approach as efficient even for a number of objects. Not every object
compressed - some small pickles are left as is.
   For more information/code search Zope mailing lists.
