I wasn't clear -- I agree that copying the egg into the bundle is the 
best solution for py2app itself.

I was arguing that it would be better to not use setuptools features in 
that way at all -- but if they're used, it's nice for py2app to support

I guess what I think causes difficulties is data files required by a 
third-party package, rather than the one my app uses -- I don't have any 
issue with data files for my app -- it's the ones in third party 
packages that you then need to install properly with py2app or py2exe -- 
that's a pain.
