I may be naive here, but I would expect the datafiles to be installed in
the same relative path as the python files. Is this not always the case?
As I pointed out in bug 2375, there is some code in setup.py (pre-dating
the support in distutils) which takes care of installing data files for
EUtils - if that actually works for the special cases you are concerned
about, maybe we should just use that for your data files too. See

That doesn't seem very elegant :(
