You might also want to take a look at the "prebuilt" binary format which we have been using for several years now, e.g.
http://www.egenix.com/products/python/mxBase/ The idea is a little different from what you describe, but works well: we essentially take a snapshot of the package after it was built and then put everything into a ZIP file. As a result, you can pick up where distutils left off after the build and continue the installation on the target machine. The prebuilt files can also be installed and uninstalled with pip if you reference the files directly. The only feature missing is support in pip for finding and downloading the right prebuilt archive from an index server. pip currently defaults to downloading the Windows builds, because it checks for the "highest" version available (for some meaning of high ;-)). Which makes me think: would it be possible to make pip more clever with respect to platform version strings ? Here's are some examples of such a version strings as detected by pip: 3.2.4.win32-py2.7.prebuilt 3.2.4.win-amd64-py2.7.prebuilt 3.2.4.linux-x86_64-py2.7_ucs4.prebuilt 3.2.4.linux-x86_64-py2.7_ucs2.prebuilt 3.2.4.linux-i686-py2.7_ucs4.prebuilt 3.2.4.linux-i686-py2.7_ucs2.prebuilt The code for bdist_prebuilt is in the mxSetup.py that comes with egenix-mx-base, in case you want to take a look.
