Thanks, I've just released a prototype:
http://pypi.python.org/pypi/van.reposync
However, as I did not want to actually execute code contained in the
tarball, I did something like this:
basedir = os.path.dirname(egg_info)
metadata = PathMetadata(basedir, egg_info)
dist_name = os.path.splitext(os.path.basename(egg_info))[0]
dist = Distribution(basedir, project_name=dist_name, metadata=metadata)
Unfortunately I had to play some guessing games to find where the
.egg-info directory was.
