Features schmeatures! I would agree, but Paul and I have decided to keep
the importer protocol real simple, at least for now. Extensions to the
importer protocol are definitely needed, but we'd like to concentrate on
the basics first. We (as in: all of us) simply need more time to come up
with a decent, coherent and simple set of (optional) extensions to the
protocol. The zipimporter object now has a get_data(filename) method
with which you can do what you want (in a less convenient way), and Paul
questions even that addition, as we might not be able to go back once
it's in the core. It could even be the subject of a PEP of its own ;-)

Also: *anything* that makes zipimporter closer to a file system is going
at it from the wrong direction. We *first* need a virtual file system,
then an import hook that can import from it, and *then* a zip back
end...
