I wonder if the package should have something in it's setup.py that says 
"I won't be compatible with anything expecting version" <2.0 ?

This would end up as metadata on pypi or in the egg/.tar.gz and 
setuptools could do the "hard work" of resolving the dependencies...

It also removes the burden of specifying maximum revision numbers on the 
consuming packages and puts it where it belongs: on the maintainer of 
the package who knows if it's going to be backwards compatible or not..

cheers,

Chris
