Why not try bundling your .py modules in a zip file and then importing the
run modules from this zip file? In that way, the package integrity is
ensured. You'd just have to ship your collaborator the zip archive and also
make sure that both of you are running the same versions of numpy, scipy,
python and other packages.

Sorry for not being more specific, the DLL actually uses Windows calls.

The Source is C. I've heard of Cython, would Cython be a more portable
alternative?

The DLL wraps a device driver, and the library of the SWIG wrapped device
driver calls is invoked from a Python app. I was trying to find how this
device driver (DLL) could be used on Linux without having to re-write the
whole driver code for Linux.
